Ultraz Winter FUGU Socks - Black

The Ultraz Winter FUGU Socks in Black are the warmest rung of ASSOS's endurance sock ladder — above Spring-Fall, Winter and the standard Ultraz. The FUGU treatment brings a wool blend to the Ultraz platform, adding insulation and natural temperature management for the coldest rides of the year. If the standard Ultraz covers deep winter, the FUGU covers the days you were not sure you would ride at all.
