When savvy sprinters and cross-country junkies want the rundown on a great pair of footwear, they jog over to North Phoenix's Runner's Den. This locally owned shop has been a go-to source for running retail in the Valley since 1978 and with very good reason. Being runners themselves, the staff at Runner's Den are fanatical about footwear. Whether you're a first-time visitor or a longtime customer looking to try a new brand, the sales associates at Runner's Den will go out of their way to find the shoes that help strengthen your stride and save you from injury. But be warned, with such careful analysis and enthusiasm for running, you will be asked to run around the building or, at the very least, jog in place at the store. From shoes and sweat-absorbing socks to fitness apparel and various types of electrolyte goo, Runner's Den remains the ultimate destination for die-hard cardio addicts.
