The rounded upper is made of premium mesh and synthetic materials. Inside the shoe, there is a soft, antibacterial Ortholite insole. The N-Durance rubber material placed under the heel increases the durability and strength of the sole during intensive use. The outsole is made using N-Ergy, an advanced technology that dynamically returns the energy put into each step thanks to an ultralight cushion. It also features the Stability Web system, which supports the midfoot and controls the dynamic twists of the foot when walking.
