GT Ultraz Winter Bootie Evo

The GT Ultraz Winter Bootie Evo is the deep-winter overshoe in the ASSOS endurance line — the Ultraz grade sits below freezing, one step warmer than the standard GT Winter Booties. On the EVO platform, it is built for the coldest rides of the year: maximum insulation over the shoe for riders who keep training when the temperature stops cooperating.
