I'm not backing them. They are hard and feel like they cause unnecessary friction. What do others think about them.
Overall, in my opinion, the Frees are still too soft, and the midsoles are still to thick for a barefoot feel. I prefer my Katana Racers, which I find more response and even more barefoot feeling. I'm training full time in the Katanas, but am always looking for a complementary shoe to use on occasion. I do like the Free's easy on-and-off, and I'd rather train in them than most conventional training shoes on the market, but I think that I'll stick with the Katanas.
