ZERO GRAVITY = AN INFINITE ENERGY RETURN
Gravity-0 is the new EXENA project which set the fundamentals for the safety footwear of the future. In the latest years the EXENA’s goal has been to try to develop a footwear where the energy return doesn’t depends from the solid and perishable compounds, but to use a natural, unlimited and indestructible element: the air.
AIR HOLE is the absolute protagonist of this project. A double density outsole studied to absorb and confer homogeneously energy, thanks to the ergonomic distribution of the air tunnels across the entire plantar arch, a sole designed to offer totally the best performance of Rebound and Anti-slip. Air-hole sole allow for a continuous air flow and so an infinite energy return. The air acts as a natural shock absorber, guaranteeing results over 60% higher than the standard regulations in terms of energy absorption and return. Important results also concerns the anti-slip, in fact the tread design is made following the latest EN 20345:2022 directives, obtaining grip values higher than 30%.
