The purpose of cushioning feet, preventing them from aching or hurting is definately done with these great cushions. I personally perfer not to have anything between my toes and just place the cushion where needed. I find if I place it outside my sock, it sometimes slips from the intended area. Inside my sock, it usually stays where it should. I guess you could velcrow or fasten it in some way, if you wore them with socks always.
