These come with a pair of booties containing liquid inside that you wear on your feet (after soaking for a few minutes in warm water) for an hour and then rinse off. The booties are large enough to fit securely and attach with tape. You can't walk around with them on so prepare to be comfy with something to do for an hour. I did these with my sister and step daughter. They both had to remove theirs after about 20 minutes because they were stinging their skin. I didn't have any problem with them. I've used 2 other brands in the past and they felt very similar. They fit better than some others and didn't leak. The smell was pleasant and light. After wearing them I rinsed my feet and after about 4 days I had some very light peeling on my toes. I waited for the sole of my feet to peel as they have in the past and it never happened. I have had deep peeling on my calluses before and that didn't happen this time, even though the solution seemed more potent. I may have needed to soak longer before using them? Compared to similar products I was disappointed I. The amount of peeling I experienced. I have another pair and will try them again and update my experience if I get better results. This might be good for someone using these for the first time if you don't have sensitive skin. #blogbooster, #rankbooster, #reviews, #productreviews, #reviewgal.
