Aerogel Insulation
Under the foot and over the toe, we use aerogel, an ultra-thin, compression-resistant and waterproof insulator, to block cold transfer from your pedals and from wind and snow.

2-Hole Mtn Shoe
This sole is designed to interface with a 2-bolt cleat for a secure ride.

Merino Liner Boot
Removable felted wool liner boot insulates while wicking moisture away from the skin. On long trips, carry a spare pair to swap out mid-ride

Carbon Fiber Outsole
Our lightweight carbon fiber outsole provides stiffness and better protects against conductive heat loss under the foot.
