The Moose is a water resistant snow boot that laces up the front. A TEX membrane is an ultra-thin layer between the shoe's upper material and the inner lining. It consists of small pores that prevent water and snow from entering the shoe. The TEX- system transports moisture vapor away from the feet through the TEX membrane, which gives a breathable and comfortable shoe. The slip resistant rubber sole features an innovative on/off OC Grip System with stainless steel studs allowing you to walk comfortably on icy surfaces. Naot's flexible, removable, anatomic cork & latex footbed is wrapped in pampering suede and molds to the shape of the foot with wear. The Snowbird collection features a 1.5" sole.
