Narrow fit, which tightens around the foot to the point where it becomes unbearable after a short while (if you have wide feet). Enormous volume at the back compared to the front. However, the worst part is that it hits me unbearably in the middle while walking... something I have never had an issue with in a shoe before. It gives a very poor posture for the foot and body and is different from how it appears in the photos in terms of volume. It didn't work for me, I recommend trying it before ordering.
