What Makes Newton Unique?


Men's Isaac Side View

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.

Men's Isaac Side View

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.

Newtons have been my shoe for 10+ years. I literally have 8 pair I rotate through right now. I train in them, I walk in them, I everyday in them, Ive even done a few Ironman in them. Ive been wanting to try these new Isaac's style for a while now as the OG Isaac where my first pair. And boy they havent disappointed. No foot fatigue, sturdy fit, look good. Id give 10 stars if I could.

Great shoe.

Almost perfect shoe. Only ding - wish the cushioning lasted, 30 days/120 miles of walking/running and there is no cushioning left in the shoe. I am sure there is a way to fix this.

These running sneakers are the best of the best. The extra cushioning is a big plus. If you are a walker, jogger, or a runner you will like this model for its super light weight and extra cushioning.
