Comfortable everyday trainer but will it hold up?

4/5

Overall

I like the zero drop, wide toe box and cushioning for my old man feet and knees. Its a heavier shoe, but the comfort factor more than offsets that for everyday mileage. My only complaint is the durability. Less than 100 miles and the stitching on the upper is already coming apart.

Totally changed my mind

Overall

Never been into the whole barefoot movement but after missing two seasons in college for PF, I tried these now as a post collegiate hobby jogger and I love them. I rotate quite a bit but if my feet are ever bothering me, I run in these and I’ve honestly seen PF go away in one run in these.
