GT Ultraz Winter Booties shoe covers are made with twinDeck construction: two layers of fabric for maximum thermal insulation and weather protection in the harshest winter conditions. The ‘goal was to create a complete weather-proof outfit that would allow the most motivated cyclists to keep riding on the road in all weather conditions. Developed from ASSOSOIRES classic GT Winter, Ultraz Winter Booties shoe covers are made with multiple layers of fabric to improve thermal insulation and protection in extreme situations.
- ThermoShell: The main material used is double-layer ThermoShell fabric. This is a softshell laminated with a polyurethane membrane and a perforated circular jersey, making it more breathable without sacrificing thermal insulation. The outer layer is treated with DWR water repellent to add an extra layer of protection.
- TwinDeck: These shoe covers are designed with a self-locking concealed zipper (cam lock) and zeroCuff edge that provides softness and no friction between legs and fabric, further enhancing the aerodynamic profile of the shoe covers.
- SportGrip: This single-elastic grippy fabric is applied to the sole for durability and to increase traction while walking.
- ZeroCuff: Raw-cut edge that provides softness and no friction between legs and fabric.
