The FormulaSoft outsole, made of dual-density polyurethane, is softer and more elastic than others on the market. It is thermo-insulated, anti-torsion and anti-vibration. The design of the sole follows the natural movement of the foot’s movements, providing maximum support and shock absorption.
Its perfect weight-volume ratio provides comfort, lightness, and technical performance that complies with the chemical-physical-mechanical requirements demanded by the EN ISO standards. The softness of the sole is felt in case of strong impact with the ground, at which point the sole gets progressively harder in order to mitigate impact shock to the spinal column.
HEAT DEFENDER PU is a compound devised to prevent heat from passing through the sole into the shoe. It resists 150° C for 30 minutes without its chemical-physical features being altered.
