WalkingPad Review: Foldable Treadmills, Under-Desk Walking & Buying Guide

Finding space for a traditional treadmill can be difficult, especially in apartments, smaller homes, and home offices. A compact walking treadmill offers another option: a machine designed for everyday movement that can be folded and stored when not in use.

WalkingPad, a brand associated with KingSmith, focuses on this type of home fitness equipment. Its product range includes foldable walking pads, hybrid walk-and-run treadmills, and higher-performance folding treadmills designed to make exercise more convenient in limited spaces.

The brand has also expanded into other home fitness products, including rowing machines, weight benches, exercise bikes, and standing-desk bundles.

But which WalkingPad model is right for your needs? How do the C2, R2, X21, and X218 differ, and what should international buyers know about electricity compatibility, shipping, warranty, and returns?

This guide examines WalkingPad’s product range and helps shoppers compare the features that matter before purchasing.

1. What Is WalkingPad?

WalkingPad is a home fitness brand associated with KingSmith, a company focused on compact exercise equipment and foldable fitness technology.

The original WalkingPad concept was developed around a simple problem: many people want to exercise regularly but do not have enough time or space for conventional fitness equipment.

KingSmith’s product history traces the early development of its compact walking machines to the first WalkingPad models, followed by foldable treadmills and more advanced walking-and-running designs.

One of the brand’s defining ideas is that fitness equipment should fit into everyday living spaces rather than require a dedicated gym room.

WalkingPad products are therefore designed around several principles:

• Compact storage and foldable frames.
• Under-desk walking for home-office use.
• Walking and running modes on selected models.
• Remote, app-based, or foot-sensing controls.
• Folding structures intended for apartments and smaller homes.

WalkingPad is not simply a conventional treadmill with smaller dimensions. Different product series are designed for different workout requirements, from low-speed daily walking to more demanding running sessions.

2. WalkingPad Product Categories

The official store organizes its treadmill range around several primary use cases.

Compact Walking Pads

These models are designed mainly for daily walking, office use, and light activity at home.

They generally have a relatively low maximum speed and a compact walking surface. Some can be stored underneath a bed or sofa after folding.

Representative models include:

• WalkingPad C2
• WalkingPad A1 Pro
• WalkingPad Z1
• WalkingPad P1

This category is most relevant to shoppers who want to increase daily movement rather than perform high-speed running workouts.

Hybrid Walk-and-Run Treadmills

The Hybrid Series is designed to combine walking and running in one folding machine.

Selected models have an adjustable handrail that can be raised for running or lowered for under-desk walking.

Representative models include:

• WalkingPad R2
• WalkingPad R3
• WalkingPad Z3 Hybrid

This format offers more flexibility than a basic walking pad, particularly for customers who want one machine for different workout styles.

Vertical-Folding and Performance Treadmills

WalkingPad’s X Series focuses more on running performance and compact vertical storage.

These products use folding designs intended to reduce storage space while offering higher speed capabilities than basic walking pads.

Representative models include:

• WalkingPad X21
• WalkingPad X214
• WalkingPad X218

The X Series is more suitable for customers who want a treadmill for running and have specific requirements for speed, running area, and user capacity.

Other Home Fitness Products

WalkingPad’s current product catalog has expanded beyond treadmills.

Other categories include:

• Foldable rowing machines.
• Adjustable weight benches.
• Exercise bikes.
• Standing desks and walking-desk bundles.

This wider product ecosystem gives shoppers more options for creating a compact home workout area.

3. Popular WalkingPad Models Compared

Choosing the right model requires more than comparing prices or the number of advertised features.

Speed, walking surface, maximum user weight, storage dimensions, and control methods can have a direct impact on everyday usability.

The following models provide a useful starting point.

WalkingPad C2 – Everyday Walking and Under-Desk Use

The C2 is a compact folding walking treadmill designed for everyday movement.

Its main specifications on the U.S. product page include:

• Speed range: 1–4 mph (up to 6 km/h).
• Maximum user weight: 220 lb (100 kg).
• Motor: 3 HP brushless motor.
• Walking area: 47.2 × 15.7 inches (1200 × 400 mm).
• Net weight: approximately 55 lb (25 kg).
• Control: KS Fit app, FootSense, and remote control.
• Power rating: 110V on the U.S. product listing.

The C2 arrives fully assembled according to the product page.

Its flat-folding design makes it easier to store under a bed or sofa compared with a traditional treadmill.

The model is particularly relevant for customers who primarily want a walking machine for their home or office.

However, its maximum speed of 4 mph means it should not be treated as a full running treadmill.

WalkingPad R2 – A 2-in-1 Walking and Running Machine

The R2 offers more workout flexibility through its adjustable handrail.

When the handrail is lowered, the machine can be used in walking mode. Raising the handrail enables its running configuration.

Its published U.S. specifications include:

• Speed range: 1–7.5 mph (up to 12 km/h).
• Maximum user weight: 240 lb (110 kg).
• Motor: 3.75 HP brushless motor.
• Running area: 47 × 17 inches (1200 × 440 mm).
• Net weight: approximately 81 lb (36 kg).
• Control: KS Fit app, FootSense, and remote control.
• Power rating: 110V on the U.S. product listing.

The R2 is a more versatile option than the C2 for customers who want both walking and running functionality.

Its trade-off is size and weight. It is heavier than the C2, and customers need to consider the available storage area and the effort required to move it.

WalkingPad X21 – Vertical Double-Fold Storage

The X21 is designed around a vertical double-fold structure.

Unlike a conventional flat-folding walking pad, the product can be stored upright to reduce the amount of floor space occupied when not in use.

Its published U.S. specifications include:

• Speed range: 1–7.5 mph (up to 12 km/h).
• Maximum user weight: 240 lb (110 kg).
• Motor: 3.75 HP brushless motor.
• Running area: 47.6 × 18.1 inches (1210 × 460 mm).
• Net weight: approximately 81 lb (37 kg).
• Control: KS Fit app and SpeedDial control.
• No remote controller listed.
• Power rating: 110V on the U.S. product listing.

The X21 is intended for shoppers who place significant value on storage design and want a more substantial running platform than a basic walking pad.

However, its vertical folding mechanism does not make the machine lightweight. At approximately 37 kg, it still requires some effort to move and reposition.

WalkingPad X218 – Higher-Speed Running

The X218 is positioned toward the higher-performance end of the WalkingPad range.

The current U.S. product comparison lists:

• Maximum speed: 11.5 mph (18 km/h).
• Maximum user weight: 300 lb (approximately 136 kg).
• Brushless motor: 5.25 HP.
• Foldable storage design.

This model is more relevant to shoppers looking for faster running sessions than those who simply need a walking pad under a desk.

As with all WalkingPad models, verify the exact regional version and current product specifications before purchasing.

Quick Comparison

Specifications above are based on the U.S. product listings. Different regional versions may have different configurations or electrical requirements.

4. Understanding WalkingPad Technologies

WalkingPad uses several design and control features across its product range.

Foldable Deck Design

The folding structure is one of the brand’s most recognizable features.

Depending on the model, the deck may fold flat or use a vertical double-fold structure.

This allows customers to store the machine in a smaller space when it is not being used.

Before ordering, compare the actual folded dimensions with the intended storage location. Check the height of the folded machine, available floor space, and whether there is enough clearance to move it safely.

FootSense Technology

FootSense is a foot-position-based speed control system used on selected WalkingPad models.

The product descriptions explain that the system detects where the user is positioned on the walking belt:

• Moving toward the front can increase speed.
• Moving toward the middle maintains a steady pace.
• Moving toward the rear can reduce speed.

This offers an alternative to adjusting speed manually with a remote or control interface.

FootSense availability depends on the specific model. It should not be assumed that every WalkingPad treadmill includes the feature.

KS Fit App

Selected WalkingPad models connect to the KS Fit application.

The product pages describe functions such as:

• Tracking workout information.
• Monitoring walking history.
• Adjusting treadmill settings.
• Viewing training information.
• Connecting with compatible devices.

Compatibility and functions can vary by model and app version.

Check the product specifications and current app requirements before purchasing.

Brushless Motors

Many current WalkingPad products use brushless motors.

The brand highlights this design for compact home fitness equipment.

Motor horsepower figures should not be used as the only comparison metric. Maximum speed, continuous operating capability, user weight capacity, belt dimensions, and intended workout intensity are also important.

A treadmill with a larger advertised motor rating is not automatically the best choice for every household.

5. How to Choose the Right WalkingPad

The most suitable model depends on how you intend to use it.

For Working While Walking

Consider a compact walking pad such as the C2, A1 Pro, or Z1.

Prioritize:

• A comfortable walking speed.
• Compact dimensions.
• Easy access to controls.
• Low storage requirements.
• Compatibility with your standing desk.

Also make sure the treadmill fits beneath the desk while leaving sufficient room for your feet and natural walking posture.

For Walking and Light Running

A hybrid model such as the R2 or R3 may be more appropriate.

Look for:

• Adjustable handrail.
• Higher maximum speed.
• Wider running area.
• Suitable user weight capacity.
• Stable placement on a level floor.

The handrail is an important feature for users who want to switch between walking and running.

For Running and Fitness Training

Consider models in the X Series.

Prioritize:

• Maximum running speed.
• Running area dimensions.
• Maximum user weight.
• Folding and storage requirements.
• Safety features.
• Power supply compatibility.

Do not choose a running treadmill based only on maximum speed. The dimensions of the running deck should also suit your stride and intended training style.

Check User Weight Capacity

Maximum user weight varies by model.

The machine should be selected based on its published capacity rather than choosing a model that only barely meets your current requirements.

For households with several users, consider the requirements of the heaviest intended user.

Measure the Available Space

A treadmill may be described as compact while still requiring substantial floor space during use.

Measure:

1. Available workout area.
2. Unfolded treadmill dimensions.
3. Folded dimensions.
4. Storage height and width.
5. Clearance around the treadmill.

For apartments, also consider whether the floor is level and whether operating noise could disturb other people in the household.

6. Important Buying Considerations for Vietnam

This is one of the most important sections for Vietnamese customers shopping for WalkingPad equipment.

The U.S. WalkingPad store and the Vietnamese market do not necessarily sell identical electrical versions.

U.S. Models Can Be 110V

The U.S. product pages for the C2, R2, and X21 reviewed for this guide specify 110V.

Vietnam uses a nominal 220V household electrical supply.

Customers in Vietnam should therefore avoid purchasing a U.S.-market version without confirming voltage compatibility.

Do not assume that every model has a universal power supply.

Vietnam-Listed Models Can Have 220V Versions

The KingSmith Asia website links to a Vietnam regional store at:

https://kingsmithfitness.vn/

The Vietnamese product listing for the X21 specifies:

• Voltage: 220V.
• Frequency: 50–60Hz.
• Speed: up to 12 km/h.
• Maximum load: 110 kg.
• Rated power: 918W.

This illustrates why customers must compare the exact regional model rather than relying only on the product name.

Different versions of the same model may have different power specifications.

What to Check Before Ordering

For customers in Vietnam, confirm the following in writing:

• Exact model and regional version.
• Rated voltage and frequency.
• Power plug compatibility.
• Maximum user weight.
• Warranty period and covered components.
• Local repair and replacement arrangements.
• Availability of remote controls, safety keys, and other replacement parts.

A machine that has the correct model name but the wrong voltage specification can create significant problems after delivery.

7. WalkingPad Shipping and Delivery

Shipping policies depend on the regional store used.

Orders From WalkingPad.com

The U.S. WalkingPad website currently lists the contiguous United States as its shipping destination.

Its published shipping terms include:

The website states that orders are generally shipped through FedEx or UPS.

These terms apply to the U.S. store and should not be assumed to apply to international buyers.

Buying Through the Vietnam Regional Store

KingSmith’s official Asia website lists a Vietnam regional link to kingsmithfitness.vn.

That local website currently advertises free nationwide delivery and an average delivery time of 3–7 days.

Delivery estimates may vary depending on location, order volume, and product availability.

For customers in Vietnam, buying through the regional channel can simplify questions about voltage, local delivery, and after-sales service.

8. Warranty and After-Sales Support

Warranty coverage depends on the purchase channel and regional product version.

WalkingPad.com U.S. Warranty

The U.S. website states that products purchased directly from WalkingPad.com are covered by a one-year limited warranty, subject to the applicable warranty terms.

Covered defects may qualify for troubleshooting, repair, replacement, or other warranty support.

Customers who purchase through Amazon, Walmart, or another retailer should contact the original seller for applicable warranty and after-sales instructions.

Vietnam Warranty Considerations

The U.S. warranty should not automatically be assumed to apply to products purchased through a Vietnamese sales channel.

For a Vietnam purchase, request written confirmation of:

• Warranty duration.
• Covered components.
• Excluded parts and consumables.
• Repair location.
• Shipping or collection costs for warranty claims.
• Expected repair or replacement process.

The local Vietnam website provides support information and user manuals, but the warranty duration and detailed coverage should be confirmed with the seller for the exact model and invoice.

Replacement Parts and Maintenance

Treadmills contain components that may require maintenance or replacement over time.

Customers should consider the availability of:

• Walking belts.
• Remote controls.
• Safety keys.
• Power adapters.
• Handrail components.
• Electronic controllers.
• Other model-specific accessories.

Before purchasing, check whether the seller can supply compatible replacement parts.

9. Returns and Refunds

WalkingPad’s U.S. return policy applies to purchases made directly through WalkingPad.com.

Eligible products may be returned within 30 days of delivery, subject to the published requirements.

Customers must generally:

• Obtain return authorization before shipping.
• Keep the original packaging where possible.
• Include original accessories, parts, manuals, and promotional gifts.
• Return the product in substantially the same condition.
• Provide proof of purchase.

Who Pays for Return Shipping?

For change-of-mind returns, customers are responsible for return shipping costs.

For verified damaged, defective, or incorrect products, WalkingPad states that it will cover reasonable return shipping where a return is required.

The company also lists estimated prepaid return-label costs starting at:

• $100 or more for selected C1, P1, C2, and A1 Pro models.
• $120 or more for selected X21, R1 Pro, and R2 models.

Actual charges depend on the product, packaging, shipping distance, and carrier.

This is an important consideration because treadmills are heavier and more expensive to return than ordinary consumer accessories.

Vietnam Returns

The U.S. return policy should not automatically be applied to purchases made through a Vietnamese seller.

The Vietnam KingSmith website advertises a 30-day return message, but its published refund information describes specific conditions for manufacturer-related hardware defects.

It states that eligible defective products may qualify for a refund of up to the full invoice amount within the first 15 days from purchase, subject to conditions concerning the original condition, packaging, accessories, and promotional gifts. Its terms become more restrictive after that initial period.

Because the marketing message and detailed refund conditions do not describe the same unconditional change-of-mind return, buyers should ask the Vietnamese seller to confirm the applicable policy in writing before paying.

10. What Does Customer Feedback Suggest?

Public customer feedback provides another perspective on WalkingPad’s products and service.

Trustpilot reviews commonly highlight the compact design and ease of setup.

Customers also describe the ability to store machines in smaller spaces as a useful feature, particularly for home and apartment use.

Positive feedback sometimes mentions helpful customer support when customers need assistance with product questions or technical issues.

However, negative feedback also includes reports of:

• Delays in customer-service responses.
• Unexpected product defects.
• Difficulties resolving technical issues.
• Problems with return or warranty handling.

These reports do not establish that every WalkingPad product will experience these issues. They do, however, reinforce the importance of choosing the correct regional seller and understanding warranty coverage before purchasing.

The experience of buying a large piece of fitness equipment depends not only on the machine itself but also on the availability of technical assistance and replacement parts.
