One of the oldest shops of its kind in Scottsdale. It was cool to be a skater or a surfer here before there were "skaters." I really dig this place. The clothes are cool, they have an abundance of Rainbow sandals, and the prevailing attitudes are the same that you would find off of the Mission boardwalk in San Diego.
For any kind of beachwear, Sidewalk Surfer is your spot. They also have a thick stock of beanies (skull caps for you east coasters) and very cool snowboard stuff.
It isn't at a discount, but clothes and shoes this rad are hard to come by.
