The MYFIT Prime liner is a masterpiece, the perfect combination of comfort, performance, and control. Lightweight and fully heat mouldable, using only the highest quality materials inside and out. The interior is anatomically shaped with a microfiber lining and the all-new 3D-shaped tongue offers perfect control right out of the box. The top lacing wraps around the cuff to give full support and is covered by the replaceable PU collar for additional stiffness and support. The liner also features a removable MYFIT shock absorber on the heel. Prime fitting and quality.
