I agree - I'd much rather wear thin merino socks in hot weather than cotton or anything else for that matter. Cotton retains moisture and quickly becomes at least clammy if not sticky and starts to rub and give me irritation around the edges. Once it's damp it is cold, and by that time it's getting into night, so I typically have to change socks during the day if I wear a pair of cotton socks from the morning. I don't see why they are so popular, except for the cheapness and I guess durability.
