I ordered a 5.5 and it is a bit small but the 6 is way too big so I settled for the smaller size. The patent or plastic detailing at the ankle gave me blisters. They are painful shoes to wear. Hopefully they will break in a bit. I had to stretch out the elastic before I could wear them. After the first ten minutes the lining bunched up under my toes. I had to peel off the lining and replace it with a store bought lining.
