You are not alone as calf pain is a common problem among runners and walkers. My advice is to ditch your shoes with "high arches" and heel padding. These shoes will only promote a walking stride with MORE impact. I suggest looking into an alternative shoe, like the FiveFingers. These shoes are designed to let you make your natural walking stride with least impact. There is no padding and no arch support, so these shoes will strengthen your feet, ankles, and calves. check out a website like FivefingerFootwear.com | Vibram FiveFingers for more info.
