I have this innate ability to pick shoes that sound perfectly fine (that is, they don’t make noise) in the store, but take on a characteristic squeak or whoosh when I get them home. When approaching someone from behind earlier this week I was actually recognized by the squeak one of my sneakers makes when I walk. I thought it might go away over time, but I have had them for a year and my left shoe still makes a small but noticable noise when I step down. And just now, a man actually stopped and pointed at my new sandals, both of which are blessed with a piston-like sound when I walk.
