While my old joint injuries cause no problems, I have had many calf cramps and tendon problems getting used to the forefoot strike. I hear that eventually all problems go away but I am still moving forward carefully.
I am wearing Newton Sir Isaacs BTW.
It has been a little tough adjusting but I am taking it easy by swithing out shoes. I am running the Country Music Marathon in Nashville at the end of the month. I might wear my new shoes.
My shoes are Altra Instinct.
