This is my 1st pair. I ordered a Size 8 and I got a size 39 EU. I am still going to keep them even though they are big but they don’t fall off from the heel or feel awkward. They feel like I am wearing a water shoe. I do NOT believe they are worth the full price at all. I will never buy at full price. They are one (1) inch wider than my Nike’s. You can sparky out your toes as there is no restricting. The sole is not thick so you will ache the first few times you wear. I was tired the 1st and 2nd days I wore, the 3rd day I felt used to them and today I wore my normal Nikes and I was like Holy Moly the sole was so comfortable yet I got home and my feet felt weird from the Nikes. They look good but they do NOT go with all my fitness wear or f I want to look cute which I do. I would definitely buy them on SALE and give them a shot.
