ShoeFilter? Six months ago, I bought a new pair of Skaters sneakers. Recently they started to make a weird "clack" sound while I was walking, and I discovered that protuding from a small hole in each sole, close to the heel, is a solid-looking metal strip, about 1cm wide and 1mm thick, looking as though it's been slowly grinding its way out. What are the strips for? Is it really necessary to reinforce the rubber with metal?
