Nordlite Ultra Running Shoe (Women)

I’ve had these for 8 months and in the last month or so my feet have started to hurt when wearing them just to walk. I only use these on the treadmill, indoors. I have never worn them outside. I run and walk. Wouldn’t call myself a runner. My previous shoes, On Clouds lasted much longer than this. Wore them until they were literally falling apart, well over a year which is why I bought these to replace. I thought it would be a better running shoe. The laces ALWAYS untie as well. And have to tie them semi loose bc if I try tie them to achieve a snug fit then they hurt the tops of my feet. But if I tie them too loose then my heel feels like it’s not secure. Have to tie them just right. Overall I would not buy this shoe again. I normally wear an 8 in a running shoe. Bought this in a 8.5
