Keep your toes toasty as you cruise along frozen trails in these Fi'zi:k winter mountain bike shoes. The waterproof eVent membrane keeps the elements from penetrating from the outside, but at the same time uses Direct Venting technology to remain breathable from the inside so you feet don't overheat or get clammy. Plus, the Artica X2's maintain a lower profile than bulky winter riding boots despite having a cozy fleece liner.
