I have run these on both soft and hard ground, and been very happy with its performance. I have high arches, but instead my  foot rolls inward more than the ideal fifteen percent (due to Genu varum?). Those types of runners "wear down their running shoes on the lateral (outside) side of the shoe towards the rear of the shoe in the heel area". Unfortunate, but this shoe is just cushion-y enough to be a dream to run in. Overall quite great for me. So far no physical complaints whatsoever -- get fitted at a jack rabbit sports if you can.
