I love these. I measured my thigh, and got the correct size but it fits a little bit. It slips down my thigh a bit, but because of the silicone it doesn't slip far or often. If I wear them higher on my thigh, (right under my bum) the roll. Because of those 2 issues I wear them at angles and it works! Since using these I have not had any chaffing. I love them so much I am going to order another pair. I recommend them to everyone!
