We're confident we offer the best fitting men's loafer sock on the market. However, if for some reason they don't fit your foot to your liking, we're happy to refund your purchase. All we ask is that you try out just one pair from your order. If for some reason it doesn't work out, return the unused pairs for a full refund. You're welcome to wash and dry the one pair as well to see if it enhances the fit before deciding.
