Feetures! Is a family company based in North Carolina and they want to get you running. The company aims to combine the best technology and design to produce truly outstanding running socks that they believe are better than anything else on the market- so much so that they provide a lifetime satisfaction guarantee. If at any point you’re not satisfied with the performance of your Feetures! socks, they will replace or refund the item. We use these socks ourselves and we can attest to their comfort, even after the longest runs (long for us that is!).
