While I won't be wearing them running till December (I run 35 miles a week and follow a strict new sneak every 3 months), I did open the box and find the shoe really flimsy.  I have 0 arch and while my orthotic will pick up a lot of slack, I really worry about the lack of cushioning in this shoe.  Could be my fault for not researching...is it suppose to model the (crazy) barefoot movement?  Time will tell.
