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)
