Two straps made from weather resistant, extremely strong sail cloth tipped with laser printed metal tabs and a ratcheting buckle for precise adjustment. The aluminum-levered buckle sits on a stainless steel base. The strap affixed to the ratcheting buckle is adjustable for different foot shapes so you can perfectly dial in how many notches you want left when the strap is at a secure and comfortable tension.
Stiffness and flex of the sole are specifically engineered in 3 areas - dubbed 3D Flex Outsole Technology - for the best combination of power transfer and fit. The center of the sole and cleat area are the stiffest part made from T700 high-modulus carbon for maximum force transfer to the pedals. Around the heel, there is slight amount of flex for positive heel support. Each side is made to have some flex and elasticity to comfortably fit a wide range of heel shapes and sizes.
