We'll see if going a full size up helps, but holy cow these were SO small. I couldn't even get them on my foot, and I am always always the same size. The strap is not stretchy at ALL, which means if you can't slip your foot through the super narrow space (which would likely squeeze the life out of your foot anyway), you are completely out of luck with even getting these on. I LOVE the look of them, especially in-person, so I super hope going up a size helps, but I'm not getting my hopes up. :/
