The ASSOS Ultraz Winter Socks P1 are high-insulation cycling socks designed for the coldest winter conditions. Their construction combines maximum warmth with high breathability to help maintain a dry, comfortable microclimate during long rides in low temperatures.
A blend of synthetic fibres and merino wool provides insulation, stretch, and natural odour resistance while retaining warmth even when wet. Triple-layer construction around the toes and midfoot increases protection in the most exposed areas, while the higher cuff extends coverage up the lower leg to reduce gaps between winter layers.

Product specifications
Composition
Size & fit
The 160-needle seamless construction wraps the foot with light compression for secure support without restrictive pressure. Triple-layer zones increase warmth without adding unnecessary bulk throughout the rest of the sock.
Care & washing instructions
Machine wash cold on a gentle cycle. Do not bleach, tumble dry, iron, or dry clean. Air dry to help preserve the wool fibres, elasticity, and insulating performance.
