when i started running a year ago i went to a reputable running store because i had no clue about shoes. they did a gait test, where they videotape you running and determine your stride type and how your foot falls. then they lined me up with a few models until i found what i liked. if they are a legit store as this one is, the return policy will allow you to exchange for a different pair if you run in em a few times and they dont fit perfectly. i dropped around a hundred bucks, but it was completely worth it, got into a shoe that was great, i would completely forget about what was on my feet when running which is perfect. and now i know exactly what type of shoe works for me. and as others said, get a separate pair of everyday shoes. find some on sale somewhere who cares how nice those ones are if they have a little support for all day activities and you will be set up. good luck, running was the best thing that has ever happened to me.
