Cushioning Level:

Cushioning Level refers to the amount of padding in the shoe’s midsole that helps absorb impact while running. Minimum cushioning provides a lighter, more connected feel to the ground, Medium offers a balance between comfort and responsiveness, and Maximum delivers the most protection and softness underfoot at the expense of ground feel.

Cushioning Feel:

Cusioning Feel describes the character or sensation of the shoe’s cushioning. Responsive shoes feel springy and energetic, helping propel each step forward. Balanced cushioning offers an even mix of softness and firmness, ideal for versatile training, while Plush cushioning feels soft and luxurious, prioritizing comfort and shock absorption.

Overview

Get ready to experience a plush and propulsive ride that's perfect for a neutral runner.

Updates and adjustments have enabled this shoe to provide exceptional and seamless acceleration in transition from heel to toe-off, ensuring a responsive underfoot experience regardless of pace. The utilisation of a soft IdealKnit mesh helps to improve breathability and comfort. 

The all new nitrogen-injected AeroFoam in the midsole increases rebound and comfort, while a deflection channel at the bottom of the midsole helps with absorption of impact, and provides a more cushioned experience. An M-Lock lacing construction in the midfoot ensures that your foot is secure. 

Key features

  • Shortened fulcrum + propulsion unit 
  • Nitrogen-infused AeroFoam
  • IdealKnit mesh upper 
  • M-Lock
