This is the best athletic shoe store I have found in Phoenix. If you are interested in talking to a sales person who knows what they are doing, and getting the right shoe for your foot (even if it is the cheapest one), this is your place.
All of the staff are very friendly and very knowledge, they will not steer you wrong. Prices are not the best however so as sad as I am to suggest it, once you find the pair that works for you buy them online after that... that way you can take the money you saved and buy those sweet super thin, thigh flashing, running shorts you have been eying!
