The treadmill located in the front window of Runnergy helps clue passersby into what this spot's all about: running. Inside, the right-hand wall is covered in running shoes of numerous styles from a range of brands. Runnergy has all of the big names, from Nike to Adidas to Puma to Reebok, as well as more unique offerings from the likes of Vibram (this company's shoes look like thick rubber gloves for the feet, with individual toes and all). Customers are invited to take a spin on the treadmill, which is equipped with a video system that enables Runnergy's friendly, expert staff to help analyze a runner's gait and then guide them to the ideal shoes. Runnergy also stocks accessories, including insoles, safety equipment, sunglasses and GPS-enabled watches. There are even racks of running apparel, and a section devoted to nutritional products and supplements. Special orders are welcome.
