Most sports grow out of a simple formula—ball plus stick, ball plus kick, or car plus explosion. Experience a rewritten equation with today's Groupon: for $25, you get $50 worth of running shoes at Dick Pond Athletics. This Groupon is valid at four locations: Carol Stream, Saint Charles, Schaumburg, and Lisle.

Dick Pond Athletics outfits runners, wrestlers, and athletes with a large selection of shoes made by brands such as Saucony, adidas, and Nike. Men's, women's, and youth track-and-field shoes allow runners to protect their feet from rough pavement and tracks littered with upside-down waffle cones. Men's shoes include Asics Gel Strike 2s ($44.95) and New Balance 760s ($74.95), and women's include Brooks Sports Lady Defyance 2s ($49.95) and Nike Lady Air Max Moto+ 5s ($53.95).

In 1969, former high-school distance runner Dick Pond made it his mission to equip athletes with high-quality, well-fitting gear. His dream still burns today, like a misplaced Olympic torch, with five retail locations, four travelling shoemobiles, and a staff dedicated to catering to each athlete's needs. The Team Bucks program returns 5% of your purchase to your team's coach at the end of the season in the form of a gift card or a goat, and Dick Pond Athletics' Runners Need Rewards program fills patrons' pockets with a $15 gift certificate when they spend more than $200.
