Assos - Ultraz Winter Booties P1 - Unisex - Black Series - 2026

Assos - Ultraz Winter Booties P1 - Unisex - Black Series

For the coldest, wettest conditions, pair with the GT EISENHERZ Ultraz Winter Bib Tights and Jacket S11, and layer with Ultraz accessories as needed for warmth and stormproof protection.

The first casualties in frigid winter conditions are your toes, and once they succumb to the stinging cold, the ride is all but over.

The updated Ultraz Winter Booties P1 are our most extreme protection for those extremities, engineered to shield against everything from icy rain on the road to fat bike adventures across snowy winter landscapes.

The body construction features the same CORE Medium textile as our GT Winter Jacket S11’s sleeves, an insulated, breathable softshell that sheds water and erases wind chill.

To further adapt to impossible conditions, we also added a second layer of protection on your foot’s leading edge with the coated WATERSHIELD, which doubles down on insulation and creates a waterproof seal where protection is most critical.

Composition:Front tip: 90%PA 10%EA; Front tip lining: External fabric 85%PA 15%EA, Internal Fabric 93%PL 7%EA; Tip reinforce: 65%PL 35%PU
