Awesome shoe! Wider toebox than the S Racer and the updated lug shape and pattern give you more traction and take much less milage to break in. A bit more rigid than the originals, but more comfortbale and versitile. Definitely worth the investment for midfoot and forefoot strikers.

I really like these shoes. The workmanship is top-notch - they use high quality materials. I have worked up to 10 mile runs in these, and use them for my tempo stuff as well. I still get a bit of calf soreness but that is slowly going away. These have really helped me perfect my midfoot strike and I find myself running with better form in my other "non Newton" running shoes that I use for long runs. I hope that with time I will be using the Newtons in all my runs.

Great shoe. Bit wider in the rear than the other model they have. Really helped my knee which was sore all the time. Legs feel less tired after the run. I have only been running in these shoes and think after 32 years of running I finally found shoes that work.

I went through 3 pairs of running shoes before I tried these. All the previous ones (NB, Nike and Asics) caused me some extent of knee pain after running no amount of cushioning helped. It was determined that I was a heel striker and Newton was recommended. I have to tell ya, these absolutely did the trick! I have no residual effects from impact and running has again become a pleasure. They do take a little getting used to, but the rewards in my case are worth a mint! With Roadrunner's exchange policy, these are definately the shoes to try!

Excellent. After running in these i can't run in any other shoe. These make all other shoes feel unnatural.

Started wearing these about 3 weeks ago. I followed the adjustment recomendations carefully as I was recovering from calf/solius strain. They fit well (true to size). I have always been more of a midfoot striker, so my adjustment went well. So far I have run up to 10 miles with no problems. I don't know if all the hype is accurate, but I really like the forefoot cushioning. Most running shoes emphasize heel cushioning and lack forefoot cushioning. So far they seem to be excellent shoes. I plan to try the winter shoe that is coming out next month and will likely consider the light weight performance shoe for races and triathlons next summer.

This shoe is my third pair from Newton. I bought this shoe mainly for a long distance shoe. They are very comfortable. The toe box seems a little bigger than the other designs. Since the heel is thicker than the other models, don't notice the lugs as much. My second run was a 10 miler...wanted to go longer but had to get to work. Ever since using Newtons, my legs don't feel as sore. Forefoot runners should definitely look into these shoes.
