Sure, wearing shoes without socks SEEMS like a good idea, until you realize that feet can sweat up to a pint of moisture per day. Ordinary shoe linings aren't designed to handle this amount of moisture, so feet get wet, sticky or clammy. SockLess Insoles keep feet comfortable when you don't wear socks. Great for women's shoes and hosiery, sneakers, 'boat shoes', loafers, etc. -- any shoes you wear without socks.
