I have a pair of Ahnu shoes and the store where I purchased them will not let me exchange them. Can you help me?

Returns for Ahnu products purchased from Ahnu.com or at a retail location before January 1, 2017 will not be eligible for exchange. Instead, you will be issued a full refund back to the original form of payment, or credit to Teva.com. We cannot issue any refunds on shoes not originally purchased through our company. We sell our products at the suggested retail price and this is the amount of credit you will be issued. We are not responsible for additional markups incurred through the original purchase location.
