interesting article and i agree with what it had to say. i only shop at fleet feet sport stores or those that specialize in marathon/triathlon training, mainly because the salespeople there are runners too, so they know all about how the body works. but i also advise runners to listen to their own bodies like the article said. it's definitely good to run around the block and try on different shoes. me being a small guy i need a lightweight shoe, and i don't over or under pronate so stability shoes work best for me, but i also have other arch supports in my running shoes to help, even though i just have regular arches. i'm kind of a brand loyalty person, so i only buy brooks running shoes ever since i started running in college. for other sports that i do i buy nike. my advice is try a lot of brands on, shoe types, etc, and decide for yourself.
