I've had re-occurring shin splints over the past couple of years, originating from me jumping rope on the concrete floor in my garage. For a while now I've just used a couple of layers of cardboard to jump on to soften the blow but now I want to purchase an actual jump rope mat to help prevent much worsening of my shin splints. Does anyone know a good mat to buy, or a place to order one? I've looked at this, http://www.megafitness.com/Everlast-Roll-up-Exercise-Mat/A/B000JF0VAU.htm, but I don't know if it's really meant for jumping rope. I;m also not sure of this ringside one is overpriced: http://www.ringside.com/DETAIL.ASPX?ID=24812 Anyone have any good recommendations? Thanks.
