Nice bounce in the heel. The shoe sticks out along the sides for extra stability, my guess. Material feels better quality (to a similar pair) and I should not wear down the fabric at the heel.
They're not real lookers, but they're not ugly. I have small feet and these make them look larger. i shall enjoy many computer coding sessions with these.
These are an amazing pair of shoes for the price, so much so that after I wore this pair, I immediately bought another pair in a different color!
