Your warranty begins from the date of purchase. Truefin has a limited lifetime warranty (excluding heel straps). In addition, the spines have a lifetime guarantee against breakage. Truefin has never broken a production injection molded glass filled nylon spine, and would like to obtain any spine that breaks for critical examination. If a user ever breaks a spine simply contact Truefin for a free replacement. The product warranty can be found in the owner's manual that is received upon purchase.
