It was Benjamin Franklin who famously quipped, "Opposable thumbs, shoes, and cookies for breakfast are the only things separating us from the animals." Tie some dignity to your feet with today's Groupon: for $20, you get $40 worth of arch support soles and accessories at Good Feet.

The experts at Good Feet, a shop frequented by pro football Hall of Famer Emmitt Smith, festoon footwear with an array of balance and skeletal-supporting accessories. Daily routine activities, such as walking on hard surfaces, running in unsupportive shoes, or competing in office-sponsored hopscotch tournaments, can throw off the body's alignment and cause discomfort. Arch-supporting shoe inserts, carefully fitted by a Good Feet staff member to contour specifically to each client's feet, help maintain a balanced, comfortable stride. The Softie support nestles feet in a cushion of dense gel and soft fabric ($29.95), while the Hug insert fuses a soft rubber compound with a stability web ($69.99) fashioned by tightrope-walking arachnids to cradle heels and bestow ache-free steps. The shop's inserts slip snugly into most shoes, including high heels, and many can also help alleviate uncomfortable issues, such as heel spurs, flat feet, and back pain.
