Size is equivalent to a US size 9. These have been worn and loved, but have lots of life left! Footbed is removable if you want to put your own soles in them. Minimalist footwear. Carbon Step footbed is built on 11/14/7 formula which means that there's an arch support of 3 mm and the toes are 4 mm lower than the heel. Super comfortable Chelsea boot with a heel pull and a large elastic gore on either side for easy entry. The more you wear them, the better they get!
