For the price I was very happy with this shoe. They fit well (12W is my normal size) and are comfortable from day one. I had no problem spending more time in them per day until they became my go-to shoe for anything but long-distance running. I ran 2-3 km in it and everything was fine, my calves and ankles hurt a little but it went away after a few hours. I think it will be some time before I can run 10km or more like I do in my Hokas. The only issue I had was the laces snapped a couple of times. It's easy enough to open the mechanism and tuck the remaining tip back into place. If you want more durability you can invest in some kind of rubber strap, <$5 here or on AliExpress.
