Transitional-weather socks tend to disappoint in one direction or the other—too thin and your feet get cold on early morning starts, too thick and you're overheating by mid-ride when the sun finally breaks through. The Spring Fall Socks P1 from Assos target that specific temperature window where summer socks leave you underdressed and winter options feel like overkill. The medium-weight construction uses a blend of polyamide and wool fibers that regulate temperature rather than just insulate, which means they adapt as conditions shift during a ride instead of locking you into a single thermal profile.

The fabric composition runs 59% polyamide, 21% wool, 15% polypropylene, and 5% elastane, giving you the durability of synthetic fibers with wool's natural temperature regulation and moisture management. The wool content here isn't just marketing—it provides genuine climate control that synthetic-only socks can't match, wicking moisture when you're working hard while retaining warmth during descents or rest stops. Assos uses their twinDeck construction in the sole area, creating a dual-layer structure that adds cushioning without bulk and helps manage moisture at the foot-shoe interface where it tends to accumulate.

Height sits in the mid-calf range, providing coverage that works with knickers or tights without the bunching issues you get when tall socks meet tight cuffs. The compression profile stays moderate throughout—enough structure to keep the sock in place and support circulation without the tourniquet feel of dedicated recovery socks. Mesh ventilation panels in the upper portion balance the insulating properties of the wool blend, preventing the clammy buildup that happens when socks trap heat without providing an escape route....
