I ordered the size large because according to the size chart, my size 9.5 should fit in it. But these are so huge I can barely walk in them.
I used the size chart to determine that I should order the size large (I wear a women’s 9.5), and these are huge. I think I could have gone with a medium. Can’t really tell you how comfy they are because they are constantly sliding down the back of my heel when I walk. Really disappointed. They are cute though.
