Jury is still out BUT, I have bought and returned 3 or 4 pairs of running sneakers from Amazon over the past 2 years and I will be keeping these. I have been wearing Asics for probably 20 years but recently have noticed that the sizing is off and the support not as good for moderately priced (under $80) sneakers. I used to be a 7.5 in Asics and could always buy that size and know they'd be fine. My last pair were bought almost 2 years ago and they were an 8.5, which I know I am NOT. But the 7.5 and 8s, my toes were hitting the front. I even recently tried a pair of Adidas, but returned them too (they didn't feel substantial enough, I can't really explain it - but they were the PureBoost Xpose).So given that it's been a 2 year journey for a sneaker that fits and feels comfortable, I am finally content. I am a walker, not a runner, but these will be fine. My only concern is that because the upper material feels like cotton, I worry that they will wear out faster. We'll see
