You fucking bet I scrub my feet. I rock climb and as most climbers do I wear my climbing shoes without socks, which also means they collect a ton of dead skin cells and sweat which makes them smell absolutely vile. I spray them all the time with a multitude of bacteria and fungus killing products, even wash them from time to time, but there’s no real solution. I just treat them as biohazard when not climbing. So yes, I make an effort to thoroughly scrub my feet to ensure they don’t retain the smell and to try to reduce how many dead cells end up in the shoes.
