The Pro MTB shoe sits near the top of Specialized’s off-road line, just below the flagship S-works and S-works EVO MTB shoes. The Pro MTB features two Velcro and one buckle strap which is a pretty common configuration these days as well as being more mud-tolerant than Boa systems. The upper is a combination of a synthetic leather called Micromatrix and nylon mesh. Specialized rates the carbon fiber mid-sole as a 10 on a stiffness scale that maxes out at 12.
