The Sidi MTB Gravel Shoes bring elegance and style to a performance package. Sidi's Tecno-3 dial system provide a customized fit with on the fly adjustability utilizing small increment changes. The wire material for the Tecno-3 dial is completely non-binding leading to intuitive and effortless adjustments. Foot protection is taken care of with the polyurethane shock absorber located in the outside ankle area as well as the Sidi heel cup which also provides better power transfer. To round these shoes, Sidi used their MTB Competition Sole constructed of durable Nylon and allowing 2 toe spikes to be installed on each shoe (sold separately). Not only do the MTB Gravel shoes look fantastic, but they also pedal like champions.
