The shoe is soft, almost too soft and without the carbon, the nylon plate feels like mush. After about my second or third run in them, I noticed how unstable they felt in the front. The foot would tend to slide in the shoe instead of plant and I'd have to correct. Did an upbeat long run with my son and noticed a pain on the inner side of my calf just above the ankle. I have seen a few other posts (limited) where others too have been injured running in this shoe. I never had this problem in the pro and I'm guessing it's due to the carbon plate in them.
Has anyone else had this issue?
