I almost bought pair of Skechers GoRun2 today. I may yet. My last 2 pair of running shoes have been Saucony Triumph 8 & 9. In looking back at training posts from last year I discovered the instance I injured my right calf. I was trying to blame it on the shoes, but I guess I can't. It was due to left hip issues and doing 300s with spikes.
Pushups (100) and shoulder band exercises with single leg balance.
