These shoes look good, but when you put them on it's a different story. There is a plastic tongue in the back of the shoe that will start rubbing against the heel and you'll get a bloody blister in a very short time! There's no way to soften this ridge, and bending it won't make it go away. The lacing system is also terrible. Basically, the laces cannot be tightened at all. If you try to tighten them, the Primeknit in the upper of the shoe puckers and it looks awfully rambling and incredibly silly. People will laugh at your inappropriate kicks. These shoes are rarely worn. I had to send them back but thank goodness I was able to because I bought them direct from Revain. Stick to Ultraboosts and avoid these NMDs!
