What Makes Newton Unique?

Level Platform

Over time, many shoe designs have become thicker, softer and heavier with greater heel heights. In the spirit of making every stride better, Newton shoes feature lower heel to toe drops to put you in a more natural running position.

 

Action/Reaction Technology

The secret formula powering the speed of Newton Running shoes is its proprietary Action/Reaction Technology. Generated by the active movement of the lugs, it creates a responsive, trampoline-like cushioning system that provides quicker bounce-back and loses less energy than a traditional foam-core running shoe.

Full Foot Cushioning

If you love the responsive yet cushioned feel of the lugs in the forefoot, you'll be happy to find out the same technology exists in the heel. With Newton Running, you get full-foot cushioning and protection.

Isaac Running Shoes

Great shoe! Just back into running after back surgery and they feel great. I have tried several other brands and they did not feel right. Glad I went back to running in Newton’s! Thank you

Awesome road trainer! Newton does it right always! I personally recommend ordering half size up from actual foot measurement.

best shoes ever

I’ve worn and run in many different brands and I have not found anything to be better and more comfortable especially for someone that is an overpronator than Newton’s running shoes and I am an avid/casual runner (60-75 miles a month).
I have the Sir Isaac’s and the Kismet 6

Great Shoes

I used to own a pair of these Isaac's a couple of years ago. Found them in a department store and never heard of them before. Awesome shoe, was in the market for another shoe and remembered Newton's from my high school days. Bought a pair for myself and a women's for my significant other. Just as comfortable as I remember, value is great as well. Keep doing what you're doing, it works.
