I normally take a 7-1/2 so that's what I ordered. As I have gained some weight, the 7-1/2 size has been snug but wearable. These were very loose. I grabbed a couple of gel pads for the balls of the feet and that helped, but they were still a bit loose. I wore these to an outdoor wedding with quite a bit of walking on a variety of surfaces. On fine gravel to the blacktop to grass to cobblestone and even flagstone. They were very stable and even with my plantar fasciitis, I was able to stand, walk and dance all day. I did notice the zippers on the back make a bit of noise when you walk, just in case that would bother you. Aside from them running a bit big, I am very pleased with these shoes.
