Groupon offers $30 worth of Okabashi Shoes for $15. This makes for some great early-season finds at a discount. Check out the company here and read about how they've made a name for themselves by keeping production in the U.S.A., using recycled materials, and recycling shoes once you're done with them. These shoes are endorsed by the American Chiropractic Association. Note that your Groupon cannot be used towards shipping costs, which run about $8. Sales tax is charged in most states.
