I originally got these in a size 13. I have another pair of New Balance running shoes in size 13 and they fit very well. These were to large. Amazingly they have size 12.5. At first I thought they fit very well. There was room for my big toe but after I went on a run I found the taper at the end of the shoe was to tight and my 3 & 4th toe were smushed causing pain. I admit this is probably due to the shape of my toes but I've not run into this issue before with other shoes. I was forced to send them back although I would liked to have kept them. Outside of the toe pain they performed as expected. It's a very minimal shoe.
