Defeet's Aireator socks have become a classic over the past few years, offering coolness, good wicking and decent durability at a reasonable price.
The socks are 60% nylon, 39% Coolmax and 1% Lycra with different weaves in different areas. Essentially, the sole, heel and toe are standard weave, the cuff – everything above your shoe line – is double thickness, and the top of the foot is more of an open weave, verging on mesh.
These Sportful Max Socks are good summer-weight socks that help keep your feet sweat-free in the warmer weather.
They're made from a mixture of Coolmax, nylon, Lycra and elastane and they're very stretchy for a close fit without wrinkles.
These aren't as light as some summer socks but the top of the foot section is a mesh weave that lets in quite a bit of cool air if you have ventilated shoe uppers. Plus, the Coolmax certainly does work to move moisture away from your feet quickly, and it dries very fast.
The Craft Cool Bike Socks are a lightweight choice for keeping your feet dry and comfortable on summer rides.
For a pair of ankle socks, there's a whole lot going on here. They're mostly nylon with some Lycra in there along with a fabric called Nanoglide that's designed to dry quickly and cool your skin.
As well as looking cool, Condor's Race socks will keep your feet feeling cool in the hot weather.
They're made from a soft micro-fibre yarn and the upper section is a light mesh that's very breathable. It's open enough to let loads of cool air through and moisture out so your feet don't feel sticky and slimy in summer heat.
