I ordered this shoe on a lightening deal, skeptical that I would keep it as I had just sent 5 pairs of sports shoes (different brands) back to another online vendor, because they were either too flat or too cushy. I've never worn a barefoot shoe and I have high arches, so I was skeptical that they could work for me. In fact, one of the five pairs I sent back was an Innov8, a shoe my flat-footed husband loves. I put these on, and like most NBs, they fit great and were true to size.

I have a treadmill desk and spend several hours per day walking, but have some knee issues that can act up. After the first day on this shoe, my legs were pretty achy and I feared they wouldn't work for me. However, I tried them again a couple of days later and had absolutely no pain/aches. I have since worn them every single day, walking for hours and hours and LOVE them. They are so comfortable that I rarely take them off until bedtime (even though we generally don't wear shoes in our house). Our house is hardwood and tile; the tile is especially hard on my knees after long periods of standing...but not in these shoes. I don't know why such a thin shoe protects my legs and feet better than my cushy shoes, but they sure do.
