I would also recommend the Running Room. Having said that, the first time I bought shoes there I was new to running and had no idea what I was doing. The person who did my gait analysis did it wrong and got me into the wrong shoe. You want to work with someone who looks/sounds like they know what they are doing. If they look new - then run away! Another place I would really recommend is the Tech Shop on 4 Street / 24 Ave SW. They have a treadmill with a camera hooked up and will record you running to give you the best advise on what type of shoe is best. Once you know what type of shoe is best (ie: neutral/cushioned; stability; motion control) then you need to try several different brands, as they all fit a bit differently.
Once you pick up your new shoes, don't forget to get some running socks. No cotton socks - use the proper running socks to help reduce the blisters.
As for pathway/treadmill running, don't worry about getting different shoes - the same ones will work for both.
Have fun and see you out on the pathways!
