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
Glad I purchase running shoes, the most comfortable shoes I’ve worn. I’m 6’ tall & 215 pounds. These shoe give me energy bounce back in every step. I would highly recommend to a person that’s a little on heavy side.
I'm a long time Gravity runner but I moved to an area with lots of steep up- and downhill segments. Sufficiently steep downhill means you pretty much have to heel-strike and brake a bit. The padding and extra heel cushion make this a better shoe for me for those runs, even if I'm still a fan of Gravity for quicker flatter runs. Great to have in the quiver.
The Isaac is very comfortable and seems to be very smooth and responsive on my training runs. They felt great on a recent half marathon.
I really like the original Sir Issac design, so when this new design came out I thought I would give it a try. It provides the same feeling as the Sir Issac but has more of a cushion. It is kind of like the benefits of the stability and structure of the Sur Issac with extra cushioned support!
I’ve been wearing Fate running shoes for probably the last 5 or 6 years. I started experiencing some knee pain and thought it was time to find a shoe with better cushion. When I received my Issac’s I felt a huge difference right away when put them on. I’ve gone for a few runs in them and several walks. I haven’t experienced any more knee pain. I think I found a new favorite running shoe.
