I have a commuter bike that I recently bought to run errands and travel short distances (two miles max, but perhaps more in the future) and I'm in the market for an appropriate pair of shoes to ride with it (current ones are falling apart). Would it be worth it for a guy like me to purchase biking shoes? If yes, what kind should I get? If not, what kind of shoes should I wear? I'd like them to be shoes that I can also wear OFF my bike when I'm merely walking around the neighborhood.
