Mavic's fury shoes offer zero compromise when it comes to speed. Ultra stiff and ultra comfortable, they're often seen on the feet of Julien Absalon and Tim Johnson, XC and cyclocross specialists, respectively. The uppers are built around a TPU frame with microfiber in between, which provides the near sock like comfort of the previous iteration of the Fury, but with a bit more sturdy feeling. The sole is a unidirectional carbon fiber that's been molded to an optimal shape and tuned to provide just a bit of give at the toe, which we've found to be nice on long rides. The Furys are compatible with mud spikes which are also included.
