I usually wear the Adidas Ultraboost but accidentally ordered the running version. This shoe is very comfortable. I wear them to work, which involves a lot of walking and the occasional sprint. I don't run or train in them but they are good for what I wear. Walking briskly made me think of hospital corridors, the plastic on the heels can be quite noisy... but it could be partly due to the way I walk, I'm not sure.
