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.

Great Shoe, unfortunately not the right one for me. Returned with plan to go back to my regular Kismet and also try the Boco for trails/hiking. Customer service was awesome and helped me to return product. They also helped me to figure out what product works best for my needs.
Thank you

Really loving my new shoes. Newton’s are so light and comfortable. They have improved the design over the toe in the Lady Isaacs compared to my last pair. The hard rubber comes up a little higher and protects my toes better. It will also help with wear.

My daughter loves these shoes!

My daughter has had these shoes in the past and asked for another pair for Christmas. They were back ordered for months, but they finally came back. I had them sent directly to her. She ran in them that day. They fit her better than any other shoe she had tried. They also offer the most footbed comfort.f
