So I bought these because I have thick thighs and chub rub is an issue. I followed the instructions on how to fit them and when I tried them on they fit perfectly. This is the first time ever that I have had that happen which is awesome! The first time I wore them was at work under a dress and they worked! I was honestly surprised even after reading a ton of reviews. I made it through a whole day with zero chafing. They didn't roll or move through out the day. I felt like they were falling but every time I would check they would be in the same exact spot, I think it's just having to get used to having them around your leg. Now why I really bought these was because I am going to Disney in a few weeks and I want to wear shorts but I don't want to worry about waddling around all day like a lunatic. Thankfully I gave these a test run at a local amusement park. I spent 6 hours in them and they stayed in place however my shorts that I wore over them spent the day riding up. When I got home and I took them off the inside of my legs were thrashed. So these are amazing if you're not going to be doing a ton of walking. Going to buy another pair so I have them to wear under dresses.
