Ultraz Winter Booties P1 are ASSOS cycling overshoes designed to handle the coldest, wettest and most extreme winter conditions. Their construction is designed to provide a high level of protection for the feet, from freezing rain on the road to fat bike adventures through snowy landscapes.

The body uses CORE Medium fabric, the same material used in the sleeves of the GT Winter Jacket S11. It is a thermal and breathable softshell that repels water and combats windchill.

To further increase protection in the most exposed area, ASSOS has added a second layer made from coated WATERSHIELD to the front of the foot. This layer doubles the insulation and creates a waterproof barrier where protection is most critical.
