The GT Ultraz Winter Booties are made with twinDeck construction: two layers of fabric for maximum insulation and weather protection in the harshest winter conditions.
Assos’ goal was to create a complete weatherproof outfit that would allow the most dedicated cyclists to continue riding on the road in any weather condition. Developed from our classic GT Winter ASSOSOIRES, the Ultraz Winter Booties are constructed with multiple layers of fabric to improve thermal insulation and protection in extreme situations.
Fabrics: The main material used is the double layer ThermoShell fabric. It is a softshell bonded with a polyurethane membrane and a circular mesh perforation that makes it more breathable, without sacrificing thermal insulation. The outer layer is treated with a DWR water repellent to add an extra layer of protection.
Construction : In addition to the twinDeck two-layer construction, these shoe covers are designed with a self-locking hidden zip (cam lock) and a zeroCuff edge that guarantees softness and no friction between the legs and the fabric, further enhancing the aerodynamic profile of the shoe covers.
