The Footprint 7mm Kingfoam Gold Hi-Profile Insoles feature Footprint's most impact absorbing and durable formula yet. Kingfoam is twice as dense as normal insoles and is the choice insole of Kevin Romar and Joey Brezinksi. While most insoles out there feature cool looking gels or cheap materials designed to look fancy, Kingfoam insoles are pure performance from heel to toe. Offering full foot and primo protection, Kingfoam also helps you skate up to two-times longer because it absorbs up to 90% of impact energy. The less impact energy that runs up your legs, the longer you can skate before getting sore. This insole is 7mm of flat King Foam and works best in vulcanized shoes.
