They're more than boots. They're insurance for your ankles. We made Instigators with a higher, more-supportive cut, then backed them up with Approach TFX outsoles and GORE-TEX liners. The Instigator GTX boot combines athletic performance with traditional Danner toughness. The fullgrain leather upper offers comfort and rugged durability while the GORE-TEX lining provides waterproof, breathable protection. Danner’s patented TERRA FORCE support system with the Approach TFX outsole provides lightweight, durable traction, heel-to-toe energy transfer, side support to enhance maneuverability, and protection from foot fatigue.
