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.

My Favorite Show EVER!!

I have been wearing Lady Issac's for 15 years! They are my absolute favorite shoe to wear on my long walks. I have a bunion and they don't give me any pain with having the wider toe box. They are also the most cushioned and comfortable shoe I have ever used....PLEASE PLEASE KEEP THEM IN STOCK!!!!

Currently on my third pair of this shoe! It’s got extra cushion without feeling heavy. I had been reserving these for days when my legs felt most tired, but lately I find myself reaching for them on a regular basis. Bonus - the bright pink brings me joy!

My favorite - please resetock!

I've run in Newtons since 2008, but these are my current favorite model. These shoes have been a lifesaver as I rehab from knee issues - I hope they are restocked or a new model is released soon, as they are no longer available in my size.

Great cross trainers

I ran my first marathon in Newtons and I have been hooked ever since. I am slowing rebuilding to running from injury and life circumstances so I needed a good shoe that I could walk in, train in, and run in. The Isaac 2 has been the perfect shoe!
