The Footprint Kingfoam Flat Insoles 5mm Kittybabe Girl are built for skaters and riders who want maximum impact protection without changing the natural feel of their shoes. With a flat 5 mm profile, they deliver extreme shock absorption while keeping a low, board-close stance. Made entirely from proprietary Kingfoam material, these insoles are designed to handle repeated hard impacts without losing performance. Their flat construction ensures universal compatibility with almost any shoe, providing real protection and consistency without affecting fit, control or balance during demanding sessions.
Performance
Performance is defined by industry-leading impact absorption. In laboratory testing under the ASTM F 1614 standard, Kingfoam absorbed up to 91% of impact energy, compared to just 53% in other performance insoles. This substantial difference helps reduce stress on feet, ankles and knees during repeated heavy landings. The flat 5 mm design allows skaters to maintain a natural foot position while benefiting from serious protection, making these insoles ideal for technical skating and high-impact riding.
Functional construction
The construction is intentionally simple and uncompromising. The core consists entirely of Kingfoam, a proprietary material engineered to withstand extreme impacts without breaking down over time. Its flat profile allows the insole to fit cleanly into virtually any shoe. The insoles are fully trimmable, allowing riders to size up and fine-tune the fit with scissors when needed. Durability, consistency and real-world performance are the foundation of this design.
Technology applied to performance
At the heart of these insoles is Kingfoam, an advanced impact-dissipating material developed to manage extreme energy forces. This exact formulation is also used by NASA on the International Space Station to protect sensitive electronics. In skateboarding terms, that translates to safer landings, reduced fatigue and dependable protection session after session.
