Seba Trix skates feature a closely fitted carbon fiber shell with an integrated liner and a unique triangle wishbone cuff. This combination of a very rigid lower boot with a more flexible upper makes the Trix an extremely versatile skate, providing good support, a close fit and solid energy transfer while at the same time allowing forward flex in the ankle. Seba's integrated liners use a combination of soft nylon knit fabric and patterned memory foam to make the skate comfortable new, and nicely fitted once broken in.
