More Foam, More Fun Our most cushioned model, the Isaac 2 combines next gen NRG+™ and Hytrel® foams to minimize impact while the sculpted rocker geometry is designed to amplify forward momentum and minimize weight. The result? An amazingly soft but versatile shoe that feels just as great logging long miles as it does wearing around casually. Next Level Technology The Isaac 2 features our innovative Split-Lug Action Reaction Technology™ to maximize rebound for a softer, smoother, more energetic ride. The 8 independent flex-lugs compress into the midsole and spring back like a trampoline, reducing impact and returning energy with each stride. Crafted For Comfort Crafted using our seamless Adaptive-Fit Air Mesh, the upper molds to the shape of your foot and lets air flow freely. And features like anti-friction lining and multi-positional lacing system create the comfort and security to make it feel like it was built just for you.
