I really like the React Infinity, but there were some issues that resulted in me having to switch back to the Pegs. I have run in the Pegs for over 20 years. Upon switching back last week, my legs feel very tired and I feel like my feet are slapping the ground.
I am a fairly high mileage runner at 70-80 mpw at 41 years old. I am not new at running and this is something that has never happened to me. What the heck is going on? Did the React Infinity slightly alter my foot strike and I am just working back to normal?
