I bought one pair of mygekks because I hate wearing the shoe liner socks that you constantly have to put back on because they slide off. The mygekks do stay in place once you use the adhesive, but if they get anything on the adhesive they do not stick anymore. They were smelly after I wore them approximately 8 times in a three-week period and using hand sanitizer did NOT fix it as they suggested on their webpage. I did not try to wash them because once you peel them off, they don’t stick anymore. The sock part that your toes go in constantly would stick between my fourth and fifth toes. If they were $5 and came with more adhesive strips they might be worth it. They are definitely not worth $18. I did not contact the company or try to get a refund. I was gullible and curious enough to try it because I have spent twenty years hassling with sock liners and I hate them.
