I only run about 1 or two miles a few days a week. It's all done on a treadmill. Currently I'm using my normal shoes, which are actually skate shoes. Sometimes my ankles will be sore after running. Would a pair of running shoes help? Or wouldn't it be worth it since I only run max two miles at a time? What are some names of decent stores that would be able to set me up with a pair of running shoes to match my foot/run pattern?
