It is a big disappointment to the shoes. I have couple Asics shoes for running. They are only used for running. Some did a few half-marathons. They are good and comfortable. But this one, only the first 3 miles run, about half an hour. It causes my left foot a blister !! The shock absorption is not really good. It may be not yet break-in. I didn't catch the review that causing a blister. The insole is too tight and too high. Yes, it really does cause a blister. Return back.
