I want to really like these shoes, very light, soft feel and responsive, but like another reviewer has said hot spots under the balls of my feet when in them for over 40 minutes. I usually tape and plaster my feet up before using them which partially helps, but I've had blisters on various parts of the balls of both feet when racing in them. Maybe I didn't get the sizing right with these as I went a half size up from my normal size due to a tight fit in the correctly sized shoes.

This shoe is perfect. No over fancy gimickery, just a running shoe with good cushioning, great response and the off road traction is akin to some purpose made off road shoes. I ran 750 miles in my last pair and only binned them because my toe came through the upper. Can be bought for £30 from some retailers.
