What Makes Newton Unique?


Women'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.

Women's Isaac

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.

Great for every day training and long runs

I always loved the long-distance Newtons but I have been having some knee pain so I decided to try these. I love them! Responsive with a cushion but not too soft, they are great for everything from sprinting to long-distance easy runs. They are light and I love the breathable outer material. The color is really vivid and cute too. I am running my first marathon in April and can't wait to wear them to the finish line!

Love this shoe for neuropathy feet. My feet must have a low heel therefore not throwing weight to the ball of the foot. This shoe has great cushioning. Well satisfied. My only desire is to have this shoe made in black or dark color, not hot pink drawing attention to the feet, haha.

Trying something new

I hadn't tried the Isaac's until now, and running in these is definitely a new experience! I'm not use to having so much cushion in the back. I've only done a few short runs in these so far, but I'm looking forward to seeing how they compare to some of the flatter pairs I typically run in. I love the vibrant pink color!

Though I do like these, I’m a fan of the originals!

Great everyday trainer

I have been spoiled by running the Gravity which I love. So I decided to try the Isaac, good for everyday easy runs.
