I have a pair of shoes that I've been running in for a while now (like 6 months, about 450-500 miles). I've noticed that the liner inside the shoe is worn on the inside rear edge of both heels almost all the way through. I really like them and they're comfortable, but I'm concerned about buying a replacement pair of the same shoes.
Perhaps this is an indication that I am in need of a shoe with more (or less?) stability or motion control?
