The Red Lion range is characterized by the new Infinergy midsole, which has brought about a real revolution in the field of safety footwear; specifically it is a mixture of thousands of closed-cell and thermoplastic polyurethane capsules that cushion the impact energy of the foot and "return" it with its movement, draining the foot, transforming the energy into a positive reaction throughout the day. The technologists adopted in the realization of the resilient energy sole allows transforming the movement done during the day into energy, increasing lightness, freedom of movement and a notable improvement in the musculoskeletal level. Lightness, safety, comfort and agility ensure natural flexibility throughout the day, leaving the foot in perfect shape.
