I have used traditional running shoes (Brooks Glycerin) for some time for both weight resistance and cardio training and decided to try a more minimal shoe with a lower heel drop - and am pleased.

Sizing:  Many reviews on this model and the earlier versions all recommended to order a 1/2 size larger.  In Nike running shoes I normally wear a 12 and are borderline small (finding 12 1/2 in Nike's can be a challenge).  The Brooks Glycerin running shoe a 12 was perfect with a 12 1/2 slightly too large.  I ordered the 12 1/2 in the New Balance MX20v3 and it fits perfect.  I have no prior experience with New Balance to compare.

Fit and Comfort:  You barely notice this shoe when wearing it due to both it's light weight and conforming fit.  The shoe easily snugs around your foot when laced and provides good lateral support.  The sole and insert provide some cushioning while still allowing you to feel the surface.  I do not plan to use these shoes for running, only weight lifting.  Traction on the sole is good and had no issues with various leg training movements (lunges, leg press, squats etc).  The fabric covering around the foot is breathable to help keep your feet dry.

Quality:  The pair I received had no visible flaws and the shoe seems well made.  As this is a very light weight shoe time will tell how long they hold up relative to the price.

Summary:  I would recommend this shoe if you are considering a light weight or minimal type shoe.  It looks more normal than some of the 5 toe style minimalist shoes.
