Speedy yet none forgiving

Raced in the first version of the Ultrafly's and thought these would have been an improvement to them. I'll give it to Nike that these are a super snappy shoe with a great upper fit. The Vibram outsole is grippy as well -- no issues there. The main issue I'm having with them is the midsole is even stiffer than the first version! I've gotten 30 miles in the shoes so far and am hoping that it's just a break-in issue, but my feet are so sore after running in these that I cannot fathom doing any ultramarathon distance race in them, especially on technical terrain.
