these shoes are great for people that really take minimalist to heart..I tried them hoping they would help my plantar fasciitis since the reviews say they do. Didn't help mine..at all. I run about 20 miles a week, and started with only a few on these..slow like the experts say..Great little shoes, and I will definitely wear them with my shorts and such, but do not like them for running! switched to forefoot strike like it's suggested, and seriously made the balls of my feet kill me. if you're used to shoes with some cushion..even a little bit..these are very different. My feet weren't happy. Run a bit small too, half a size up from your normal would be better. Ordered my regular size and my toes were resting on the hard plastic sole where they're molded together with the insole..not comfy. Best thing about them is the zero drop..that I do like! :)
