I purchased these for working out at the gym. I love how they look and would have found them comfortable if the soles were of equal size! The left heel sole is shorter than the one on the right by at least a half inch which makes it dig into the side of my foot. If the shoe had been through any type of quality control this would have been spotted, but it obviously hasn't and therefor wasn't. I'm gutted because if it weren't for this, I'd be wearing them daily.
