Lets start off by saying that I did not want to like these shoes, but after giving them a shot they are my “go to” shoes now! The last 2 -3 yrs I got used to wearing minimalist shoes so anything slightly heavy was a “NO” for me. At 9.1 oz per shoe & over 1lb these would typically be too heavy for me. My first impression when putting these shoes on the first time was how comfortable they felt. I loved the way the Internal slip-on construction fits the foot like a sock without causing excessive pressure, the stretch air mesh tongue is one of the most comfortable I have tried in any shoe. It makes me want to use them without socks.
