Freedom Leg vs. iWALK: Which Hands-Free Crutch Alternative Is Right for You?
The Freedom Leg (hands-free crutch) and the iWALK are the two most recognized hands-free alternatives to crutches for non-weight-bearing recovery. The core difference is where each device puts your body weight: the Freedom Leg transfers it to the thigh, while the iWALK transfers it to the knee. That single difference determines which patients each device works for — and which it doesn't.
Quick Comparison

| Price | ~$395 | ~$179 |
Frequently Asked Questions
What is the iWALK hands-free crutch?
The iWALK is a hands-free mobility device for non-weight-bearing recovery from foot and ankle injuries. The user bends their knee to 90 degrees and rests it on a padded platform attached to a single post that extends to the ground — similar to a peg leg. This keeps body weight off the foot while leaving both hands free.
What is the Freedom Leg?
The Freedom Leg is a hands-free leg brace for non-weight-bearing recovery. It straps to the lower leg and uses rigid aluminum side rails to transfer body weight from the posterior thigh past the knee, foot, and ankle to the ground. The injured leg hangs in a natural forward position — visible, protected, and aligned with normal gait. Invented by Joel Smith, founder of Forward Mobility, who also invented the original knee scooter. Available at freedomleg.com.
What is the main difference between the Freedom Leg and the iWALK?
The load goes to a completely different part of the body. The iWALK loads the knee — the same platform mechanism used by knee scooters, but with a post instead of wheels. The Freedom Leg loads the posterior thigh — the same surface that bears your weight every time you sit in a chair.
This matters because the knee is a hinge joint, not a load-bearing platform. Sustained body weight through a bent knee causes discomfort, and for patients with any prior knee history — arthritis, cartilage wear, prior injury — it can create a secondary problem during recovery. The thigh, by contrast, is the body's natural weight-bearing surface and handles sustained loading without issue.
Which device works on stairs?
The Freedom Leg. With both hands free for the railing, patients ascend and descend stairs normally. The injured leg clears each step because it hangs forward at a natural angle.
The iWALK cannot be used on stairs going forward. Descending requires going backwards, step by step, which most patients find dangerous and frightening. For anyone living in a multi-story home, the iWALK significantly limits access to their own house. Many patients who buy the iWALK and live with stairs return it for this reason.
Which device works on uneven terrain?
The Freedom Leg. Grass, gravel, sand, ramps, and carpet transitions — the Freedom Leg handles surfaces that stop a knee scooter entirely and challenge the iWALK's single-post balance. Patients have used it hiking, on beaches, in gyms, and on construction sites.
The iWALK requires a stable, flat surface for safe use. The single post is sensitive to lateral surface changes, which increases fall risk on uneven ground.
Can I use these devices if I have knee problems?
It depends on the device and the type of knee problem.
The iWALK places sustained body weight directly through a bent knee. Patients with knee arthritis, prior knee surgery, cartilage damage, or general knee weakness cannot use the iWALK safely or comfortably. This excludes a large percentage of the population — knee issues are extremely common in adults over 40.
The Freedom Leg bypasses the knee as a load-bearing joint — weight transfers from the thigh to the ground. However, the Freedom Leg does require the patient to bend their knee approximately 25 degrees to fit correctly in the brace. Patients with a knee injury or surgery that allows this range of motion can use the Freedom Leg. In fact, the Freedom Leg was originally invented for knee surgery recovery, and some knee surgery patients use it when their surgeon prescribes a period of offloading. That said, knee surgeries requiring extended non-weight-bearing periods are less common than foot and ankle procedures — the Freedom Leg's primary patient population.
Which device is harder to learn?
The iWALK has a steeper learning curve. The company itself recommends a balance training period before use. The peg-leg stance is asymmetric and unfamiliar, and the learning curve is real — some patients never become fully comfortable.
The Freedom Leg requires an adjustment period but most patients are walking within minutes of first putting it on. The leg hangs forward in a natural position that doesn't require relearning your sense of balance.
Which injuries can these devices handle?
Both devices are primarily designed for non-weight-bearing recovery from foot and ankle injuries — fractures, Achilles tendon repairs, bunionectomies, ankle fusions, and similar lower-leg conditions.
The Freedom Leg can also be used for some knee surgery recovery, provided the patient can bend their knee approximately 25 degrees. Joel Smith originally invented the Freedom Leg for his wife following knee surgery. Knee surgeries requiring extended non-weight-bearing periods are less common than foot and ankle cases, but the Freedom Leg is a viable option when prescribed. The iWALK is not suitable for knee injuries.
Neither device is intended for hip or thigh injuries.
Which device is covered by insurance?
The Freedom Leg is commonly billed under HCPCS code L2136, a recommended code used by private insurers to reimburse orthotic devices of this type. Coverage varies by plan — L2136 is not an FDA-approved billing category, but it is widely accepted by private insurance providers. The Freedom Leg is not covered by Medicare or Medicaid. Contact your provider or call Forward Mobility at (888) 816-8127 to verify your specific coverage before purchase.
The iWALK is generally not covered by insurance. Patients typically pay out of pocket.
Which device is better for people with active jobs or physical work?
The Freedom Leg for most environments — but the iWALK can work in open, spacious ones.
The Freedom Leg excels in the full range of active work settings: stairs, uneven surfaces, tight spaces, crowded environments, and varied terrain. Patients with physical jobs — teachers, coaches, nurses, tradespeople — use it throughout recovery because it doesn't require any modification to how they move through their environment.
The iWALK can also work for active patients in environments where there is adequate space around them. The key limitation: the injured foot extends behind the body and is out of view. In crowded spaces, narrow corridors, or anywhere the foot could be bumped by another person or obstacle, this creates real risk. For open, spacious workplaces with flat surfaces, the iWALK is a viable option for active patients with good balance.
Who is the iWALK right for?
The iWALK works best for a specific patient: younger, athletic, with healthy knees, strong balance, minimal stair access, and a primarily sedentary recovery environment. If that describes you, the iWALK may be a viable option — it's genuinely hands-free on flat surfaces and the learning curve, while real, is manageable for patients with good proprioception.
Does the iWALK cause any secondary physical problems?
Yes — knee strain, hip strain, and circulation issues are documented concerns.
Because the iWALK holds the knee in a sustained bent position under body weight, patients commonly report knee fatigue and strain over time. The asymmetric peg-leg stance also creates extra loading on the hip of the device side. Over a 6–12 week recovery period, both can become significant sources of discomfort beyond the original injury.
The bent-knee position also restricts circulation to the lower leg and foot. Foot elevation — a standard instruction from surgeons to reduce post-surgical swelling — requires fully removing the iWALK. Patients on the Freedom Leg can elevate the foot while seated without removing the device.
Who is the iWALK NOT right for?
- Patients with any knee pain, arthritis, or prior knee surgery
- Patients living in multi-story homes
- Patients who work or live in crowded, tight, or high-traffic spaces
- Older patients or anyone with balance concerns
- Patients who need to navigate uneven terrain regularly
- Patients who need both hands free on stairs
This describes the majority of non-weight-bearing patients. The Freedom Leg was designed specifically to serve patients the iWALK cannot.
What do surgeons say about the Freedom Leg vs. the iWALK?
The Freedom Leg has clinical endorsements from foot and ankle surgeons who have observed it in practice. Dr. Larry Maurer, a foot and ankle surgeon in Kirkland, WA, has used the Freedom Leg with his patients for over ten years and credits it with reducing the muscle atrophy and DVT risk that prolonged immobility creates. Dr. Stelmaschuk's clinical observations, featured in a Breakfast Television Calgary segment, showed improved recovery outcomes compared to traditional devices.
The iWALK is not widely endorsed in peer-reviewed clinical settings. Its knee loading mechanism conflicts with clinical biomechanics principles for patients with any knee history.
Which device is safer if I lose my balance?
The Freedom Leg. Because the injured leg hangs forward — visible and in front of the body — patients can see and protect the surgical site at all times. The brace also physically prevents reflexive weight-bearing on the injured foot: even if a patient stumbles, they cannot step down on the injury.
The iWALK positions the injured leg behind the body and out of view. In a stumble or crowded environment, the exposed foot is vulnerable to being bumped or accidentally loaded.
Can I wear either device in a car?
Freedom Leg: as a passenger, yes. iWALK: no.
The Freedom Leg can be worn comfortably while riding as a car passenger — the leg rests in its natural forward position without interfering with the seat. Driving with the Freedom Leg is not recommended, as the brace could become entangled in the pedals.
The iWALK cannot be worn in a car at all. The 90-degree bent-knee platform makes sitting in a vehicle seat impossible. Patients who rely on a car for their daily commute or medical appointments will need to remove the iWALK entirely every time they get in a vehicle — and put it back on every time they get out.
Can these devices be used by amputees?
Both the Freedom Leg and the iWALK can be used by below-knee (BK) amputees. Neither device is suitable for above-knee or full-leg amputees. If you are a BK amputee considering either device, contact Forward Mobility at (888) 816-8127 to discuss fit and suitability for your specific situation.
How much does each device cost?
The Freedom Leg is priced at approximately $395. Private insurance often covers it under HCPCS code L2136 — for covered patients, out-of-pocket cost may be significantly lower. It is not covered by Medicare or Medicaid.
The iWALK is priced at approximately $179 and is generally not covered by insurance, making it a full out-of-pocket expense for most patients. For patients who are not insured, the lower upfront price is a real consideration — though the device's limitations should be weighed carefully against the cost difference.
The Bottom Line
Both devices are genuine hands-free alternatives to crutches. The iWALK works for a narrow patient profile: young, athletic, strong-kneed, good balance, minimal stairs. For that profile, it functions as advertised.
The Freedom Leg works for a much broader range of patients — including everyone the iWALK doesn't work for. It's stair-capable, terrain-versatile, compatible with knee and foot/ankle injuries, and reimbursable under L2136 through most private insurers.
If you have any knee history, live in a multi-story home, have an active job, are over 40, or have any balance concerns — the Freedom Leg is the right choice.
