I'd suggest ordering a bunch from runningwarehouse.com because you get fre shipping and can return them free of charge no shipping. The website also has great pics of the shoes with a 360 view so you can get as great of a view of the shoe as you can from a website. Not to mention runningwarehouse has product vids and "sneak peaks" of the next stuff coming out. And their selection is very very good, for example they carry brooks launch and brooks t6 racers and some other shoes I love.
As for running stores, I give kudos to Marathon Sports locations in the Boston area. They have some great staff who are nice/great people, always real runners themselves and also some NCAA runners or former NCAA runners and best and most important of all I haven't found them to be arrogant but just helpful when you need it. Also, unlike other runningstores I've been to if you just want to look around yourself at the different shoes they carry they leave you alone without swarming you too quickly. Again I'm not sure about this gait analysis stuff, if a shoe FITS IT FITS!!! Arthur Lydiard says in his book Running To the Top that pretty much everyone is neutral when running barefoot and the best running shoe for you is some simple flexible rubber slab underneath.
Another running store I went to I wasn't as impressed at all. the salesman there swarmed me immediately as I entered the store, looked at the shoes I was wearing casually, and tried to suggest a shoe of the same brand to me based on this. Also, their shoe selection at this other running store was terrible - they only had brooks shoes in the stability category and few neutral running shoes. Also they had very few racing/xc flats.
At any running store the technical running clothing and stuff is going to be pretty expensive. Every once in awhile you can get something to grab but whatever I mean if you need running clothing immediately that day, want to try it on, and don't want to order it and wait for it off runningwarehouse.com, its not too bad.
I noticed from runningwarehouse.com and all other merchants that like all Nike drifit tees at any merchant is like 40plus dollars MSRP so I look at Brooks and New Balance technical tees and stuff with the runningwarehouse discount is incredibly cheap. The Nike stuff is even as cheap as you can get it with the discount at runningwarehouse.com. Kudos to runningwarehouse.com - they are the best place period and other running stores' worst nightmare!!! :)
