Seems better for waking than running. Very lightweight with softer materials. Nice, simple style. *Be aware* these RUN SMALL. I found a great pair here but unfortunately they didn't fit.
A lot of descriptions online say "true to size", but the reviews about sizing are inconsistent. I normally wear 7-7½. I took a chance ordering a 7 and they were way too small. I think I would need an 8. That's how much smaller these felt. I could barely get my foot into it. I later tried on a women's size 9 in store (these are discontinued and it's the last size they had) and on the other foot I had on a different style Nike in 7½ and I could barely tell the difference. So, my suggestion is to order one size up if you want to be comfortable and not kill your feet.
