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.

A solid choice

If you're looking for traction and cushion, this is a solid option. I started using them for my easier runs, but I found I enjoyed wearing them more as a casual walker instead of a running shoe. I prefer the Gravity and Distance models for running.

Newton Isaac 2

A really great shoe! Very comfortable and well cushioned. Similar to the original Isaac but the overall feel of the shoe is more comfortable. Love the blue color too - very vibrant!

Helped Me Break a World Record -Jack LaLanne Jumping Jacks Challenge

As an athletic scientist, I am an admirer of Sir Isaac Newton. As a result, I was delighted to learn about an athletic shoe company named after Newton and a shoe named after Sir Isaac. A couple of months ago, I was invited by the Jack LaLanne Family (Jack was a good friend of mine when he was alive) to participate in the Jack LaLanne Jumping Jacks Challenge to break the world record of the most number of people to do Jumping Jacks simultaneously. The goal was to do 98 Jumping Jacks at once in honor of Jack's wife, Elaine LaLanne's 98th Birthday. I needed to find a shoe with a lot of cushion to do this challenge. So I ordered the Men's Isaac 2 shoe right away, trained with it, and wore it on the day of the event. I couldn't successfully do the 98 Jumping Jacks without the Men's Isaac 2 cushioning. It worked perfectly for me!. We broke the World Record with 9,363 jumpers worldwide participating. Thank you Newton! - Dr. John Westerdahl

The quality of shoe is top notch. With a company name such as Newton, one only can expect their products to have the newest and greatest science and technology molded into their shoes and they do not disappoint!
