Behind the Overcurve R4’s lies an advanced construction technique: a resilient, polyurethane-laminated material is combined over a comfortable mesh, reducing energy loss and providing long-lasting foot support where it’s most needed.

• Outsole: R4 outsole – carbon injected nylon, stiffness index 7
• Overcurve: asymmetrical construction that ergonomically conforms to the foot’s anatomy
• PU laminated mesh upper: enhanced ventilation with support where needed
• Weight: 230g (size 42 - 1/2 pair)
