I'm sending these shoes back. I've been wearing Adidas for 20 years now. I wore the Supernova Glide which they no longer make. I read that this shoe was one of the replacement parts for it. It's very uncomfortable. There is a decorative stitching from the fingertips to the sides. The stitches rubbed against the toes, an uncomfortable feeling. I could only wear them around the house for 30 minutes. However, the stitches on my big toe caused a blister. Next I'll try Ultraboost. Hope they work.
