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.

Usually walk in Fate or Kismet, tried these because of the color (pink). I have very flat feet and found I was walking too much to the inside arch. Considered returning these but changed the insert to a Dr Scholl’s which fixed the problem. Now LOVE these shoes!

Most comfortable shoe ever! I stand on my feet all day at work and these are the only shoes that keep my feet from hurting. I wish there were more colors, and bring back the black!
