What Makes Newton Unique?
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.
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.
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.
What Our Runners Think
I was hesitant to try this style, but it turns out I love it! It is much more comfortable than the older Lady Isaac style, and I would have been hard pressed to come up with such a review! I've been a loyal Lady Isaac wearer for several years now, and this style is even better than the last!
Newton never disappoints me. I always wore when running and now that I am older and unable to run as in the past, I use this for work at my part time job which requires walking on concrete floors and they are a blessing.
These are my second pair of Newton’s in the last year and I love them! I have the Gravity 12 that I use for trail running. I bought the Isaac’s for road races. I have only ran in them once on the treadmill, no issues. And used them for a 10 mile hike. No complaints or pains. Highly recommend! They’re fabulous.
When are Lady Isaac S coming back
The Newton Women’s Isaac is very comfortable and has the perfect toe box for my feet. I use a lift in the left shoe so U ordered a half size bigger and they are perfect!!!
