The idea for exercise came from the practice of running from predators, just like the idea for bottled water came from hunting raindrops. Exercise the original workout with today's Groupon: for $25, you get $50 worth of running shoes and apparel at One Step at a Time in Decatur. The store is open Tuesday–Saturday from 11 a.m. to 7 p.m.

One Step at a Time owner Charles Cope channels his lifelong love of running into an emporium for athletic shoe, apparel, and energy products. Runners and walkers alike can slip into a snug pair of Thorlos Experia socks ($11.95), support the arches with original Powerstep insoles ($29.95), or block out glares from jealous, stroller-bound babies with an Asics running hat ($18). Running and walking shoes ($75–$130) by popular brands such as Brooks, Mizuno, Asics, and New Balance jump off the shelves to outfit feet in need of a comfy, high-performance home, and custom fittings are available for those with thin, wide, or excessively normal feet. Cope provides attentive customer service within the white walls of his welcoming shop, utilizing 50 years of running experience to help pavement pounders find the shoes and accessories that fit each individual's personal exercise habits.
