The i-Run team says

Technologies

• Zero Drop

  Flat cushioning. The Zero Drop platform offers total cushioning and places the heel and forefoot at the same distance from the ground. This natural balance helps keep the feet, back, and body posture aligned to minimize shocks. Additionally, the Achilles tendon and lower calf muscles, weakened by wearing running shoes with elevated heels, are strengthened.

• Foot-Shaped Toe Box

  The FootShape toe box allows the toes to spread naturally and comfortably while keeping the big toe straight. This improves stability and increases the propulsion strength of the toes, optimizing running performance.

  Advantages:

  - The big toe remains straight, providing greater stability and increased propulsion strength.

  - The toes can spread naturally and comfortably.

  - The foot naturally compensates for any excessive pronation.

• StoneGuard

  Integrated under the insole, the StoneGuard material protects the foot with flexibility on uneven terrain, deflecting rocks under the midsole for a smoother and more stable run.

• TrailClaw

  Studs positioned directly under the metatarsals at the front of the shoe for optimal traction both uphill and downhill.

• GaiterTrap

  Self-gripping strap that allows for easy attachment of the gaiters to prevent debris from forming under the shoe.

• Balanced Cushioning

  The Balanced Cushioning platform positions the heel and forefoot at the same height from the ground. This natural base helps to properly align the body, maintain better form, and promote low-impact ground contact.

• MaxTrac

  Outsole that perfectly combines grip, traction, and durability to effortlessly cover the miles with ease.

• FootShape Medium Fit / Standard Fit

  Shape and design halfway between a classic fit and a tailored fit.
