**New ASSOS Fall/Winter 2026 Collection item | October 2026
ASSOS ULTRAZ Winter Booties P1 are shoe covers for riding in the coldest, wettest, most extreme conditions, updated with the latest proprietary softshell and increased protection on the forefoot and toe area.
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 a 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 MILLE GT Winter Jacket S11’s sleeves, an insulated, breathable softshell that sheds water and erases wind chill. To further adapt to intense weather conditions, there is an 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.
