Your SheepFeet Foot Frame is warrantied for 2 years from normal wear and tear. Because your feet are constantly changing with age it is a good idea to get a new impression, and pair of SheepFeet after 3+ years. You need to always check for rocks under your orthotics. If a rock gets in your boot and you continuously walk on it, it will cause the Foot Frame to break and that will not be covered under the warranty.
The Dura cover, XC2 padding, and Heel Stabilizer are warrantied for 1 year. It is a good idea to do a SheepFeet restore every 1-2 years. Due to sweat, and wear and tear, your SheepFeet can get a little gross depending on how regularly you use them.
