Prosthetic Chafing & Skin Irritation: What Amputees and Adaptive Athletes Should Know

When runners talk about chafing, the conversation usually goes to the same places: inner thighs, sports-bra lines, underarms, waistbands or nipples.

For someone wearing a prosthesis, using a wheelchair or moving with adaptive equipment, friction can look very different.

A residual limb may move slightly inside a socket. Sweat can build beneath a liner. A jersey can rub the same area through hundreds of wheelchair propulsion cycles. Straps, braces and equipment can repeatedly contact skin.

Different bodies. Different equipment. Different movement.

But the basic problem is familiar:

Repeated movement + friction + time can irritate skin.

Sometimes reducing that friction can help.

But sometimes what feels like “chafing” is telling you something more important about prosthetic fit, pressure or skin health.

Knowing the difference matters.

Why Can Prosthetics Cause Chafing and Skin Irritation?

A prosthetic socket has a difficult job.

It needs to connect the body to the prosthesis securely enough to transfer force and control movement, often while being worn for hours at a time.

Inside that environment, skin may be exposed to pressure, friction, heat, perspiration and repeated movement.

One issue is known as pistoning—when the residual limb moves up and down inside the prosthetic socket while walking. The Amputee Coalition explains that pistoning can pull on the skin and cause damage. Perspiration can also contribute to heat rash and abrasions.

Skin problems are also relatively common among lower-limb prosthesis users. The Amputee Coalition identifies issues including pressure sores, blisters, dermatitis, folliculitis and skin breakdown, and recommends regular inspection of the residual limb.

That means the first question shouldn't always be:

“What can I put on this?”

Sometimes the better question is:

“Why is this happening?”

When Friction May Be a Sign of Something More

A recurring red spot, blister or sore shouldn't simply become part of wearing a prosthesis.

Persistent irritation may indicate an issue with pressure, socket fit, suspension, alignment or movement within the prosthesis.

The Amputee Coalition recommends reporting blisters and redness that doesn't go away after removing the prosthesis. Continued pistoning is also a reason to have the fit checked by a prosthetist.

Amputee Coalition: Wound Care — Preventing Infection →

The Amputee Coalition's Skin Care 101 guidance advises that if skin breaks down, the prosthesis should not be used until the problem is addressed, and the person should contact their doctor or prosthetist.

That distinction is important to us at Run Slick.

Run Slick is an anti-friction product.

It is not a prosthetic-fitting solution, wound treatment or substitute for a prosthetist.

An anti-friction product cannot fix a socket that is creating too much pressure or moving incorrectly.

If you are experiencing recurring redness, blistering, broken skin, significant pain, drainage or another persistent skin problem, address the underlying issue first.

So Where Can Reducing Friction Help?

There are also situations where friction itself really is the problem.

Intact skin may repeatedly rub against clothing, a strap, an edge of equipment or another surface during movement.

That's the type of problem Run Slick was designed to address.

Run Slick is a clear, lightweight anti-friction roll-on that creates a thin, silky layer on the skin where rubbing occurs. It is designed to be applied to clean, dry, intact skin before friction becomes irritation.

It is not designed to be applied over open blisters, broken skin or significant existing irritation.

For prosthetic users, there's another important consideration: the liner, socket and suspension system work together.

If you're considering using any anti-friction product inside the prosthetic interface or underneath a liner, talk with your prosthetist first to make sure it will not interfere with the fit or function of your system.

But prosthetic users and adaptive athletes can also experience friction in plenty of places outside the socket itself.

That's something we've started learning directly from the community.

What a Wheelchair Basketball Player Taught Us About Friction

Run Slick started in endurance sports.

But once more people began testing it, they showed us friction problems we hadn't originally considered.

One of the clearest examples came from a para athlete in the Shepherd Center wheelchair basketball community.

Wheelchair basketball requires constant upper-body movement. Athletes propel, accelerate, stop, turn and defend by moving their arms again and again.

He explained:

“I’m constantly moving my arms back and forth creating a ton of friction.”

Usually, after a few games, he said his jersey rubbing against his body left his underarms and nipples burning.

After testing Run Slick, that didn't happen.

He also told us that the product didn't dry up during play and that the added low-friction layer helped.

That use case didn't come from a brainstorming session.

An athlete showed it to us.

And that is exactly how we want Run Slick to continue learning.

Fred Pegues Put Run Slick to the Test

We heard something similar from Fred Pegues, a double amputee, after he tried Run Slick.

Fred didn't immediately give us an opinion. He wanted to use it long enough to see whether he experienced any negative effects.

In his review, one phrase stood out:

“protected the skin”

Fred reported that the products went on smoothly, that he experienced no negative setback, and that he would recommend Run Slick to the clinic he attends.

One person's experience doesn't prove that a product will be appropriate for every amputee. Every residual limb, prosthesis, liner, suspension system, skin condition and activity level is different.

But Fred's experience matters to us because it comes from someone actually living with these challenges. It's another piece of what we're learning.

Even Elite Para Athletes Deal With Skin Breakdown

This isn't simply a problem for people who are new to prosthetics.

In October 2026, Paralympic gold medalist Ezra Frech publicly discussed developing a painful blister at his amputation site while competing on Dancing With the Stars.

Hours of dancing in his prosthesis had put significant strain on the skin of his residual limb, enough that he was visibly limping during rehearsals.

Ezra Frech is not affiliated with Run Slick, and we're not suggesting that he uses the product.

His experience is relevant because it shows how repeated movement and hours of prosthetic use can put significant stress on skin—even for an elite adaptive athlete.

Adaptive Movement Creates Friction in Different Places

Not every adaptive-athlete friction problem involves the prosthetic interface.

The wheelchair basketball example is important because his problem wasn't necessarily the wheelchair.

It was what the movement caused his clothing to do against his skin.

The same principle can apply to underarms, chest, waistbands, thighs, straps, braces, harnesses and other areas where clothing or equipment repeatedly moves across intact skin.

Those are very different problems from a pressure injury or poorly fitting prosthesis.

And that's an important boundary.

We aren't talking about treating wounds.

We're talking about reducing avoidable rubbing before it becomes a problem.

Start With the Skin, Not the Finish Line

One of the simplest habits for anyone using a prosthesis is also one of the most important:

Check your skin.

The Amputee Coalition recommends regular residual-limb inspections and paying attention to redness, cracks, rashes and anything that looks unusual. If discomfort develops during the day, removing the prosthesis and inspecting the skin can help identify a developing problem early.

This matters because the goal shouldn't always be:

Keep moving no matter what.

Sometimes stopping is the right decision.

A better goal is:

Move comfortably and sustainably—and pay attention when your body tells you something isn't right.

That philosophy fits Run Slick better anyway.

Hard is okay.

Unnecessary friction isn't.

Why This Community Matters to Us

Run Slick's connection to adaptive movement started on the road, not in a marketing plan. Founder Felipe Niada has spent years volunteering with Ainsley's Angels, running alongside Riders and their families.

Callie was the first Angel Rider Felipe ever pushed in a race. Her joy during that race—and her family's reaction afterward—reinforced something that has stayed with him ever since: movement can create participation, connection and belonging in ways that go far beyond a finish time.

Maddie's family reinforced the same lesson from a different angle. With family members who have different physical abilities, Ainsley's Angels gave them something meaningful they could all participate in together.

Those experiences are part of why Run Slick believes movement should be more comfortable and more accessible. You can read more about that story on our Adaptive Movement page →

Another Resource for Amputees: Nike's One Shoe Bank

For an amputee who only needs one shoe, buying footwear in pairs can create another unnecessary problem.

That's why we recently published a separate guide about the Nike One Shoe Bank, a program designed to help people who need only a left or right shoe.

Our guide explains what the program is, how to contact Nike and what information to have ready when making a request.

It doesn't sell Run Slick.

It doesn't need to.

It's useful information for a community we're spending more time listening to.

And useful information should be shared.

Frequently Asked Questions About Prosthetic Chafing

Why does my prosthesis cause chafing?

Several things can contribute to skin irritation, including pressure, friction, sweat, changes in residual-limb volume and movement inside the socket.

One potential cause is pistoning, where the residual limb moves up and down within the socket. The Amputee Coalition notes that this movement can pull on and damage skin and recommends contacting your prosthetist if it continues.

Is redness from a prosthesis normal?

Temporary redness can occur, but redness that persists after removing your prosthesis should not be ignored.

The Amputee Coalition recommends reporting blisters and reddened areas that do not go away when the prosthesis is removed.

Can Run Slick help with prosthetic chafing?

Run Slick is designed to reduce surface friction on intact skin.

Whether it is appropriate for a particular prosthetic-related friction point depends on where the friction is occurring and why.

If the irritation may be caused by socket fit, pressure, pistoning or another prosthetic issue, talk with your prosthetist rather than simply trying to lubricate the area.

Before using an anti-friction product underneath a prosthetic liner or inside a socket system, discuss it with your prosthetist.

Can wheelchair users use Run Slick?

Run Slick can be used on intact skin where clothing or gear repeatedly rubs.

A wheelchair basketball player who tested Run Slick specifically reported that it helped with friction caused by repeated arm movement and jersey contact around his underarms and chest.

Can I apply Run Slick to a blister or broken skin?

No.

Run Slick is designed primarily to help reduce friction before irritation develops.

Do not apply it to broken, bleeding, severely irritated or otherwise damaged skin.

What is the Nike One Shoe Bank?

The Nike One Shoe Bank is a program designed to help people who need a single left or right shoe rather than a pair.

We've created a separate Run Slick guide explaining the program and how to request a shoe.
