Comments: These are my first Newton's, and I was unprepared for the crazy bounce from the first step which set off a giggle fit. I was concerned about the fit as it felt like my toe was coming out the front when first tried on. This feeling disappeared while running, however, as the forefoot pads push the foot toward the heel. Newtons changed my stride, making it shorter, higher, and faster. I step much more lightly which tends to unnerve walkers I pass. There wasn't any adjustment period for my muscles, but it took about 10 runs to learn to trust the pads. I haven't tried these on longer runs yet--the max has been 10 miles. I'm getting caught out by winter weather and the Newton Gravitys are impossible on even light slow. So far that's the only downfall; they are otherwise a comfortable, light shoe that has made running fun again.

Comments: At first, I wasn't sure about Newton, having previously been a heel striking, Asics Nimbus user (model 12 was my FAVORITE). I have completely adjusted from being a heel striker to a mid-foot striker using the Newton Gravity shoes. I will say, I bought the 2012 (red/black/yellow) model from a local running store at the full price of $175, and also ordered the 2010 model (blue with red laces) from Running Warehouse (as they were $99 at the time of purchase). Personally, I like the 2010 model better. I am a size 10 1/2 in all running shoes, but, as advised, bumped up to size 11 for the older/2010 model. The older/2010 shoe fits much better for me, with the lug position truly at the ball of the foot (the 2012 edition seemed just too far back, and yet size 11 in the 2012 edition was just too big a shoe). I have tried running mid-foot in other shoes (Saucony Cortana 2; which I bought just to wear around becuase of a HUGE local running store discount), and the Newton really does give a bounce, or at least, less impact when landing. I run approximately 6 miles usually 2-3 times a week, and I think if I did less lower body gym workouts (squats, lunges, etc.), having less muscle soreness would allow more running.

Comments: I am mainly a cyclist but have periodically tried running as cross training. Running aways hurt something--knee, achilles, back, etc. I have now tried the Newton Sir Issac about 5 times running 2 to 3 miles each time on asphalt. No pain. I do not even get tired. Works for me. For the first time in 40+ years I actually enjoy running and look forward to it. Thanks!

Comments: As a triathlete I normally run with Zoot but, I found I was going through them too quickly - 250 miles maximum. So, with that said I bit the bullet and bought a pair of Newtons figuring since they were marketed as a "high mileage trainers" I would get the life span of two pairs of Zoot. I got about 350 miles out these and then they went in a major way, it was like someone flipped a switch. The shoes feel "flat" when I run in them, no more cushioning in the forefoot which is really irritating my plantar. Don't get me wrong, these are great shoes and I ran two marathons plus training in them but, I was hoping for more miles at this price. I normally run about a 7:30 mile (distance) at a 90 cadence and I am 5'11 and 160 lbs. Looking back at things, I wouldn't recommend these shoes the cost per mile for me was about $0.50 and for Zoot it was closer to $0.40. I might try the cheap Sir Issac model and see if it does better. The shoes do have fantastic breathability and they felt great for the first 300 miles but, neither of those traits justifies the price in my opinion.

Comments: I transitioned into the Newton line of shoes beginning with the Sir Issac which made it easier to adjust to the Gravity trainer (higher actuator lugs). I'm on my third pair of Gravity trainers and find this latest model to be superior to the last. A very well built shoe and extremely comfortable. This shoe is a great trainer yet light enough for racing. The shoe is roomy enough to accept my custom orthotics. My only fuss is the color selection, as Newton colors are rather bright. Overall a great product.
