Description
Assos Endurance Socks S11
Assos’s warm-weather workhorse sock
The S11 platform replaces the older GT Socks C2 as Assos’s core cycling sock, built around the same core promise — lightweight, breathable, cooling — but with a more durable construction. Odour-resistance yarns are mapped across the foot to give light compressive support at the metatarsals, arch, and ankle, while the 18cm (7in) cuff is designed to sit right under most kit without needing a separate length option.
Fabric and performance ratings
Assos rates the S11 5/5 for breathability and 5/5 for packability, with 4/5 for quick-drying and 1/5 for insulation — confirming this is built specifically for warm-to-hot riding conditions (Assos lists it for temperatures above +21°C) rather than cooler or shoulder-season rides. Fit is rated Regular.
Construction and fit
Seamless construction eliminates friction points, giving a low-profile, ultra-soft feel with no exposed seams to cause hot spots on long days in the saddle.

Wetsuit Sizing
What's the difference between the Endurance S11 and the GT Socks C2?
The S11 is Assos’s updated replacement for the GT Socks C2 — same core idea (lightweight, breathable, seamless), but a more durable construction and a slightly taller 18cm cuff versus the C2’s 16cm.
What conditions are these socks best for?
Rated 5/5 for breathability and 4/5 for quick-drying, with an insulation rating of just 1/5 — these are built for warm-to-hot riding above roughly +21°C, not cold or wet conditions.
Will these rub or cause blisters on long rides?
No — the seamless construction is designed specifically to eliminate friction points for a low-profile, ultra-soft fit over long distances.
