The NUORO rigid sole is an anatomical outsole made of high-density polyurethane to ensure stability and durability on athletic surfaces. The design includes an ergonomic profile with a pronounced arch and a slightly raised toe to facilitate forward propulsion. The lower surface features traction grooves and grooves arranged in an optimized configuration to provide grip during start-ups and changes of direction. Nine pre-arranged points for the insertion of interchangeable studs provide versatility for both natural and synthetic surfaces. The flat upper with internal grooves facilitates adherence to the insole and evenly distributes pressure. The logo is embossed on the heel for discreet and long-lasting recognition.
