Knee Sleeves help keep chaffing down under your knee braces. When you sweat, the moisture is a sure fire way to get road rash or slippage of the brace. When you forget your knee sleeves, it can suck. If you do, here’s a quick fix in a pinch.
Take an old pair of moto socks, cut the toe off, then figure out where to cut the calf portion. From there, the ankle section works at the knee bend. It does slip a bit throughout the day, but it’s better than having nothing between your knee brace and your precious skin!
