I have a pair of Ultraboost 20s and love them. I was so excited to get them that I met the delivery driver at the bottom of the driveway. Unfortunately, Adidas has changed the fit of these shoes. I usually get 7.5 and my fingers never cramp. My toes were right on the end of these boots and that's just not good. I like the look but I returned them and bought a different brand. I wish they would leave Ultraboost alone and give the new version a different name.
