I'm kind of old school about a lot of stuff and approach anything I'm not familiar with skeptically. Twenty different kinds of sneakers, each designed for increasingly particular niches of activity? Yeah, right. I've always worn cotton socks for riding, but I see more and more people swear by task-specific motorcycle socks. Most are polypropylene, Lee Parks features some made of bamboo. Are all the poly ones equivalent (just buy the cheapest)? Anyone try the bamboo ones? Mostly, does either type make much of a difference?
