This is a very good shoe if you never had the original. It is good to have the DMX10 on the market even if it isn't the same shoe. Runners might find this shoe somewhat bulky and the ankle support is lacking. My original shoes form '97/'98 from took over 450 miles before wearing out. My new DMX10 is showing significant wear at 110 miles. As I stated earlier, this is a really good shoe if you don't compare it to the original!
