The Sidi Dominator Fit has set the standard for off-road cycling shoes throughout the last decade. Inherent to the Dominator is Sidi's renowned comfort and fit which has been frequently emulated by other shoe manufacturers. Despite many attempts, only Sidi exhibits a truly slipper like feel due to the use of their highly breathable and durable Lorica fabric. Sidi's Soft Instep Closure System and padded tongue provide an extremely secure fit without any undue pressure on the foot's instep. Along with the caliper buckle, Sidi's High Security Velco straps use interlocking polymer teeth to secure the foot without velcro slippage. To both protect the heel and provide further foot stability, Sidi uses a reinforced heel cup. Sidi's heel cup, borrowed from their motorsport technology, is also designed to increase the shoes durability for off-road use.
