Assos Endurance Socks S11 - Deadly Berry

The Endurance Socks S11 are Assos engineering applied to one of the simplest pieces of kit. Built as a durable, mid-height cycling sock platform, the S11 Endurance replaces the earlier GT sock silhouette with a construction that emphasises cooling, breathability and a secure fit suited to long rides and everyday use. The Deadly Berry colour offers a bold, jersey-friendly option without moving into compression-sleeve territory.

At an 18 cm cuff height the Endurance S11 provides deliberate coverage above the ankle and sits neatly under bib shorts for a contemporary road look. The knit is intentionally lightweight and ventilated so that the sock helps regulate temperature inside modern road shoes while remaining robust enough for regular use. The result is a sock that manages internal humidity and heat without feeling bulky or constrictive.

Assos has focused these socks on ride comfort and durability rather than high-compression performance. The engineered fit holds the sock in place through pedalling and does not interfere with shoe fit or pedal contact. That makes the Endurance S11 a practical choice for riders who want a dependable, well-fitting sock for everything from weekday training to long weekend rides.
