AK DEVA Gore-Tex Boot Liner I purchased this used last year. I bought it to wear inside my boots when riding my motorcycle. It's a size LL. I usually wear 26.5cm sneakers with a 3E width, and there's about 1cm of extra space in the toe. It was also comfortable even when wearing thick socks. I used it once on a touring trip, but I didn't use it in the rain. I'm selling it because I bought new waterproof boots and no longer need it. It doesn't take up much space, so you can keep it with your rain gear for hiking or touring and be prepared for sudden rain. These are completely waterproof socks made by Akagi Kogyo, using Gore-Tex, so they don't get stuffy. They are now discontinued.
