I'm a run/walker w/bad knees and find this sole style does a good job of absorbing impact and preventing knee pain.

This particular shoe has lightweight "spacer fabric," so I wouldn't buy it to run outside in frigid weather.

The metal grommets prevent you from lacing the shoes as tight as you'd like because the laces keep slipping.

The shoe is a tad short. I wear 9.5 medium, and my big toe touches the tip. but i haven't had discomfort from wearing it and would still buy it again.
