This composition is durable, lightweight and provides unmatched compression to extension capabilities for their compact size. These lifetime boots are found sealed up tight, continuing to shed dirt and moisture on assemblies still in service for over 3 decades. Yes, high quality product like this does cost more, but with that kind of service record it's hard to argue their value. Occasionally accidents do happen, so if you damage a boot we offer a complete selection of replacements for all Stiletto Steering models.
