I'm an avid runner, and finally checked out Super Jock 'n Jill from a friend's recommendation. In the past, I just bought whatever was on sale at Big 5, but the service, fitting, and advice you get from the employees is unmatched. Every employee seems to be very knowledgeable, patient, and passionate about running.
I bought a pair, took it home, and was unhappy after a few runs. With NO QUESTIONS ASKED, they apologized and allowed me to fit a new pair, which I am very happy with. ...and they're very reasonably priced. Sure, you might find the same pair of shoes online for $15-20 cheaper, but the service you get here is incredible. Most pairs I tried on were right around $100.
