I ALWAYS fit in size 9 (US) shoes, so I figured 9-9.5 would be perfect for me, per usual. Wrong. The front of my foot couldn't even fit inside the clog. However, since these are quite affordable compared to other hospital shoes, I decided to order a size up. This time I could fit my foot into the shoe, but the shoe entrance is so tight, that my foot cannot get deep enough the shoe for my heel to fit on. The shoe is definitely long enough as I can feel space in front of my toes, but I can feel circulation being cut off at the entrance to the shoe and my heel slips out with every step. Super annoying.BTW, I don't wear wide shoes, so this isn't an issue of not ordering the wide size. I can only presume these are intended for skeletor feet.
