The MYFIT Size adjuster is the perfect little helper to adjust the size of the foot vs the shell or liner size. If you have some gaps between your foot and your skate this EVA molded part will help you to fill the gap and get more performance and comfort out of it. It provides also added protection for your toes and nails. The perfect tool for younger skaters who buy skates a size bigger for growing feet but still have full control and power transfer. With the flex cut design one size fits all. MYFIT - upgrade your ride
