What Makes Newton Unique?


Women's Isaac Side View

More Foam, More Fun

Our first super cushion shoe 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.

Women's Isaac Bottom View

Next Level Technology

The new Split-Lug Action Reaction Technology™ is designed to maximize rebound for a smoother, more energetic ride. Equipped with 8 independent flex lugs that compress and spring back like a trampoline, they reduce impact and return energy with each stride and work in harmony with the XPS+ Peebax plate to keep you stable and in total control.

Women's Isaac

Crafted For Comfort

The Adaptive-Fit seamless air mesh molds to the shape of your foot and lets air flow freely; while features like a non-friction lining and multi-positional lacing system provide the security and comfort that makes it feel like it was built just for you.

I have five new pairs. All but one fit. Due to damaged feet the last one cannot accommodate the twists and turns of toes but each one has a slightly different effect and I do like them so much. For very old damaged and neuropathied feet this is wonderful and I even wear them to church. The ministers always noted my old red ones. Thank you for your kind service.

Great!

Only running shoes I wear. Was wary about the change but they are even better

So comfy!

I found my new go-to running shoes! My hunt for a good pair of vegan running shoes lead me to the Isaac shoe by Newton. I have tried a few others in the past and this one so far I am really enjoying.
