I am a Merrell Salesperson for my day job:
The Barefoot Concept:
These shoes are designed to have NO support. True, the shoe wraps your foot so tightly that it feels like there is a great support. However, this is just how it feels. In time, it will build up the muscles in the foot and in between the bones, helping to strengthen the arch itself.
The pace is great, I wear mine everyday. They are a little tiring on concrete all day though. Size about a 1/2 size up and you'll be a lot happier. When you are standing, lift your toes straight up and your longest toe should just hit the edge of the seaming. The toe box is designed to be very roomy so the foot can "splay" out as you walk. You will land more on the balls of your feet, with a more even displacement of weight. The shoe is designed to discourage the heel - to - toe strike.
For someone that is just starting into the barefoot line, I would recommend the Bare Access Arc or particularly, the Dash Glove (Road Glove for men). The Dash/Road is designed for concrete and asphalt.
If you have any other questions feel free to PM me. Also, if you don't have someone that sells Merrell in your area, until May 1st the website is doing free shipping, just type in the code: SPRING12. The website also does free size exchanges.
Hope this helps.
