Hand Made in ITALY. As with the ratcheting buckle version, the M5 Boa features uppers comprising Microtex synthetic leather, mesh, and anti-scratch genuine leather. Fizik places the latter around the toe box and heel cup in order to resist abrasion while traversing talus slopes on foot. The lightweight mesh fills the voids between the leather sections for a heightened sense of cooling ventilation. And at the interior, the soft Microtex liner provides a lasting comfort over bone-rattling trails in balmy conditions.
