What Makes Newton Unique?

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.

What Our Runners Think
Love these shoes!!
The style is more recognizable than the previous NYC edition shoe. The upper seems slightly more flimsy than the last pair I had. otherwise is a great shoe. I should mention that I don't run- I buy these for the style. Also I was able to fit my orthotics in well (as with previous editions)
Love the look and feel of these shoes - felt good on my long runs.
These shoes are extremely comfortable, and great for running. After my first mile in these shoes I feel like I can run longer and faster. Some of the best Newton’s I have owned, and also their style is great!
I love Newton Running shoes, these were a little tight for my usual size, buy a 1/2 size up
