A higher level

The Mastia is designed for cutting edge performance and control. One of the most aggressive shoes in the Tenaya line, the Mastia is a split-sole shoe combining down turned precision and sensitivity with edging power. The Mastia features Tenaya's first-ever thermally molded heel cup for maximum precision in heel hook performance. The split sole construction allows for extra flexibility while reducing edge deformation. The advanced technology and construction minimizes pressure on the toes while maximizing transmission of power. The shoe features a single Velcro strap closure system for quick entry/exit and maximum foot retention, along with a sticky rubber covered toe box for increased protection and grip.
