i am not convinced they work [SEP] i have worn these the last few nights and they are quiet comfortable i normally cannot stand anything on my feet when i sleep as they get hot and feel itchy having dry and thick skinned heels must be a genetic thing as i have struggled with it my whole life every morning after my shower i have to put some kind of moisturizing product on my feet i have tried everything from vitamin e shea butter and urea creams but i wanted to step it up a notch and put something on while i sleep so i bought these at a pair they are quite the investment when they arrived they came with zero instructions just a plastic bag i had no idea what to do with them i did not even know what the ingredients were i had to come back to the listing to find out it had different oils infused in the gel pad even then it suggested we soak and prune our own feet then apply a moisturizer so after my self done pedicure i put these on and slept comfortably the next day my feet did feel softer but i beg the question was it form these socks i have my doubts as i am pretty sure it is because i scrapped all the dead skin off and put my own moisturizer on them not impressed with these socks at all
