These were the most uncomfortable slides I have ever had on. The little nubs on the insole are extremly hard and feel like your standing on small stones. I only had them on my feet for about 3-5 minutes and after taking them off it felt like I was still standing on them 15 mins later... Went back for a refund the same day I got them. The old adage that you get what you pay for is very true. They are inexpensive, but not worth the price. I wouldn't wear them if they were free...
