How much a difference can they make?
That was my attitude toward cycling-specific socks for years. Sure, cycling-specific apparels like jersey and padded short improved both on-bike performance and comfort considerably. But a pair of socks? I’ve been using standard cotton socks for years, feeling just fine even on 200+ km rides—until I gave compression socks a try recently. While perhaps not as significant as cycling-specific short and jersey, I must admit, they do make difference—especially on hours of constant, continuous pedalling motion.
