I've been wondering this, because I feel so bad when I go into a running store just to try it on and jog in it around the store, with all the help the people do for me, then say something like "well i don't think i'm going to get them today." Is it not good or proper i guess to go into a running store and do that, or is it fine? The reason I ask is because I could try the shoes on there, and then go online and get a MUCH better deal. Any thoughts?
