If you ride with knee braces, you know the feeling. Halfway through the second moto the back of your knee starts to burn, the straps are digging in, and by the end of the day you've got red raw patches that make getting back on the bike next weekend a chore. Knee brace rubbing is one of the most common complaints we hear from riders, and the good news is it's usually fixable.

Here's a rider-to-rider rundown of why knee braces rub, what actually helps, and how to set up your gear so you can focus on the track instead of your skin.

Why do knee braces rub in the first place?

A knee brace is a rigid frame strapped tightly to a leg that's constantly moving, sweating and flexing. Put those things together and friction is almost guaranteed unless something sits between the brace and your skin. The usual culprits are:

• Bare skin or thin socks under the brace. Straps and pads rubbing directly on skin is the fastest way to chafe.
• Sweat. Wet skin and wet fabric create more friction than dry ones, which is why rubbing often gets worse later in the day or on hot Aussie summer rides.
• Movement and slipping. If your sock or sleeve bunches up or slides down, the brace ends up sitting on folds of fabric or bare skin.
• Poor brace fit or strap tension. A brace that's too loose moves around; one that's cranked too tight creates pressure points.
• Boot interaction. The bottom of the brace meets the top of your boot, and if the layers underneath are bulky or creased, that's another hot spot.

How to stop knee brace rubbing: 7 fixes that work

1. Wear a proper knee brace sock

This is the big one. A knee brace sock is a long sock that runs all the way up past the knee, so there's always a layer of fabric between your skin and the brace frame, hinges and straps. Regular MX socks stop below the knee, which leaves the area the brace sits on exposed.

Our GOATBRAND MX knee brace socks were designed specifically for riding with braces: a ventilated upper to help with airflow, a polyester and lycra blend for a snug fit, and a design that sits smoothly under the brace to help minimise friction and irritation. You can wear them under the brace, or roll the top over the brace for a cleaner look.

2. Get the sizing right

A sock that's too big will bunch and crease under the brace, and creases are exactly where rubbing starts. Too small and it'll want to slide down your leg. Check your size against our sizing guide before you order. Our socks come in two sizes (S/M and L/XL), so it's worth taking thirty seconds to measure up.

3. Pull everything smooth before you strap in

It sounds obvious, but a lot of rubbing comes from rushing in the pits. Before you put the brace on:

• Pull the sock all the way up and smooth out any wrinkles behind the knee and around the calf.
• Make sure the heel of the sock sits properly in your heel so it doesn't twist.
• Fit the brace with your knee slightly bent, the way it'll sit on the bike.

4. Check your strap tension

Your braces should be snug enough not to migrate down your leg, but not so tight they're cutting in. Follow your brace manufacturer's fitting guide, and if you're unsure, get your local MX shop to check the fit. If a brace keeps sliding no matter what, it may be the wrong size for your leg, and no sock will fully fix that.

5. Manage sweat

Sweat makes rubbing worse, especially in summer. A breathable, ventilated sock helps, and a few simple habits help too:

• Bring a spare pair of socks for long days and swap them at lunch.
• Loosen or take off your braces between motos to let your legs dry out.
• Wash your socks after every ride day so salt and dirt don't build up in the fabric.

We've written more on this in our guide to the best motocross socks for hot weather and sweat.

6. Keep your socks in good nick

Worn-out socks lose their stretch, go thin in high-wear spots and start slipping, which brings the rubbing straight back. If your socks have holes, bobbling or loose elastic, it's time for a fresh pair. Rotating between two or three pairs also helps them last longer.

7. Look after the skin you've already rubbed

If you're already chafed, give it time to heal before your next big ride, keep it clean, and cover it up so it isn't rubbed again straight away. If a sore gets worse, looks infected or isn't healing, see a GP or pharmacist rather than riding through it.

Knee brace socks vs regular MX socks vs sleeves

Riders often ask whether they really need a dedicated knee brace sock. Here's the simple version:

• Regular MX socks are fine if you ride without braces or with knee guards that sit inside your pants. With braces, they leave the brace contact area uncovered.
• Brace sleeves go over the knee under the brace, but they're an extra layer to manage and can slide independently of your sock.
• Knee brace socks cover foot to thigh in one piece, so there's one layer to set up, no gap between sock and sleeve, and less to bunch up in your boot.

For most riders wearing braces, a full-length knee brace sock is the simplest way to stop rubbing.

Picking the right knee brace socks

When you're shopping, look for:

• Length: it should comfortably come up above the top of your brace.
• Breathability: a ventilated upper helps on hot days.
• Snug, stretchy fit: so it stays put and doesn't crease.
• Correct sizing: check the brand's size chart, not just your shoe size.
• Durability: socks that hold their shape for longer stay comfortable for longer.

And let's be honest, they should look good too. Riders love designs like the Ducky Kneebrace Socks, Grim, Muerte and Koala Kong. Browse the full range in our knee brace socks collection.

Quick pre-ride checklist

1. Clean, correctly sized knee brace socks on.
2. Socks pulled up and smoothed, with no creases behind the knee.
3. Braces fitted with your knee slightly bent and straps snug, not crushing.
4. Boots on and the brace bottom sitting cleanly at the boot top.
5. Spare socks in the gear bag for long or hot days.

FAQ

Can I wear knee braces without socks?

You can, but it's the most likely way to end up with chafing. A full-length sock gives you a layer between the brace and your skin.

Should the sock go over or under the knee brace?

Under the brace. Some riders roll the top of the sock back over the brace for a tidier look and to help keep things in place.

Why do my knee braces still rub with socks on?

Check that the sock is the right size and not creased, that it's in good condition, and that your brace fits and is strapped correctly. A brace that's the wrong size can rub no matter what you wear underneath.

What size GOATBRAND MX socks should I get?

We offer S/M and L/XL. Check our sizing guide to find your fit, or get in touch and we'll help you out.
