Traditional gymnastics wrist supports that support the back side of the wrists from hyperextension and help if you are experiencing wrist pain. These are sold in pairs. The level of support is customizable and we include 2 different types of foam inserts, along with plastic inserts if you want them very stiff. The contoured shape makes for a sleek fit and the metallic leather ages quite well and doesn't look as "worn out" as the suede supports can get. Follow the sizing chart based on weight but if you are "in between" sizes it's probably better to go up since these are velcro and can be tightened.
