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.

Newton Lady Isaac Didn't Disappoint

This is my 3rd pair of Newtons and this pair is amazing. From the first step, I felt like I was walking on clouds. The colors are cute and I'm fairly picky. My last pair of Newtons lasted me through my first Marathon without any blisters or foot pain (and beyond). I'm a forever fan of Newtons!

These are great!

My only word of advice in all other models that I have used (stability) I order an 8.5 (half size larger than I normally wear) however next time I order Lady Isaac I will bump up another half size they are slightly narrower than others.
