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
I've run in Newtons since 2008, but these are my current favorite model. These shoes have been a lifesaver as I rehab from knee issues - I hope they are restocked or a new model is released soon, as they are no longer available in my size.
I ran my first marathon in Newtons and I have been hooked ever since. I am slowing rebuilding to running from injury and life circumstances so I needed a good shoe that I could walk in, train in, and run in. The Isaac 2 has been the perfect shoe!
I have worn Newton's for years, various styles. These are great! I mostly walk long distances now. These were comfortable and supportive from day 1. You can't go wrong with Newtons. Bring more colors!
This is my first time trying this model and per usual, they are fantastic! I really love the added cushion for longer runs with the same Newton quality and feel!
These shoes are amazing… I actually bought these to wear at work where I put many miles on walking around the hospital… They are cushiony lightweight and I love the color. Thank you for making these.
