Rev'it! Astro Shoes The Astro Riding Shoes from Rev'it! blend moto-centric rider features into the style of a techy athletic high top. With the exception of the 3D air mesh toe covering, the Astro Shoes use nubuck leather for the entire upper. Side panels are perforated. Thermoformed heel and ankle protectors are built into the boot's upper to protect the rider during a gravity penalty on the bike or on the courts. A thermoformed cap on the inside of the toe is mirrored by a leather shifter pad on the exterior. OrthoLite engineers the X40 insole for on- and off-the-bike comfort that is cushier than a foul line dunk.
