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.

Best shoes ever!!

I suffered from shin splints for years and tried every motion control shoe out there. These are the only shoes to ever work for me, I love them and literally can't run pain free without them!!

Only shoe for me!

The low heel to toe drop and overall support keep my foot from pushing forward. These have kept me going for the last several years! So thankful for them!

Newton Lady Isaac S

These are the best tennis shoes I've ever had! This is my third pair, after being fitted in a running store with the Newton Lady Isaac over 10 years ago. My only wish is that they were produced in a larger variety of colors, including a more neutral option. Fantastic shoe, and the only one I've ever found that works well with the high arches of the instep of my foot.
