It's okay to ask questions. That’s what we’re here for. Below is a list of the most commonly asked questions and answers. If you can't find what you’re looking for here or on the relevant pages, feel free to contact us.
Choosing a Model
Which shoe is right for me?
We recommend choosing your Newton based on several factors.
Your foot type
How comfortable you are with a midfoot technique
If you have ever worn Newtons before
Primary use for the shoes
If you have questions about which model is best for you, send us a message here and we will do our best to match you up with your Newton soulmate!
How can I find my foot type?
Great question! If you don't know your foot type, you can either stop by your local specialty running store for an analysis or check out our video for finding your foot type. Look up your local Newton retailer here.
Which models are designed for a more neutral foot type?
Runners with a more neutral foot type will want to take a look at the Aha, the Fate, the Gravity IV, and the Distance IV. Not sure of your foot type? Check out our video here.
Which models are designed with added stability for overpronation?
Runners with overpronation will want to take a look at the Energy NR II, the Kismet, the Motion IV, and the Distance S IV. Not sure of your foot type? Check out our video here.
Which models are designed for trail use?
The BOCO AT and BOCO SOL are our two trail specific models that will offer the best trail-specific performance. The BOCO AT has a water-resistant upper and better cold weather protection while the BOCO SOL has a more breathable mesh upper for warm-weather use.
Which models can be used as racing flats?
The MV3 and Tri Racer are our short distance racing flats and are great for 5k-10k distance racing. These super-stripped-down flats are designed with a 0 mm drop and a very minimal upper to give you a light-weight race day feel. The Tri Racer features some triathlon specific modifications such as elastic laces, a perforated pull tab, integrated tongue, and more seamless upper that make it great for Sprint or Olympic Triathlons.
Sizing and Fit
What size should I get?
We recommend basing your size off of your current running shoes. Measure if you have a full thumbs width of space from the top of your longest toe to the end of the shoe. If you have that much room, stay in the same size for your Newtons.
If you are unsure of your current size, please use the ShoeFitr application (located on each shoe page) in order to help with an accurate size estimate. Our shoes run true to athletic sizing so most runners stick with the size that they typically wear in an athletic shoe.
How do I know if my shoes fit properly?
The proper fit in your Newtons should give you about a thumb's width from the end of your longest toe to the end of the shoes. This should ensure that the raised lugs on the midfoot are fairly centered under the ball of your foot to allow you to hit your sweet spot on every stride!
Is it okay to use orthotics or inserts with my Newtons?
Yes. Simply remove the insert that comes with the shoes and replace it with your over-the-counter insert or custom orthotic.
For custom orthotic information, please contact the Newton Running Lab at 303.494.0321
Shoe Features and Details
What does POP mean?
POP stands for Point of Power and refers to the different types of cushioning and level of responsiveness in our different models. This is the “sweet spot” in the shoes.
So tell me more about POP 1.
POP 1 refers to our most responsive lug platform. The POP 1 platform will have isolated and squared-off lugs based on an elastic membrane and hollow chamber to give you the most responsive ball of the foot platform. Found in our Mileage and Speed trainers, the POP 1 platform is designed to give you a highly responsive and dynamic ride.
And POP 2?
Our POP 2 platform will feature the same elastic membrane and hollow chamber like the POP 1 platform but with rounded and articulated lugs to help guide you onto the sweet spot on the ball of the foot. Found in our Core trainers, the POP 2 platform will still offer a great responsive feel, but with a slightly more relaxed ride due to the beveled lugs.
Last, but not least, POP 3?
The POP 3 platform, found in our Gateway trainers, is based on a foam-filled chamber designed to provide a slightly softer and less pronounced sweet spot on the ball of the foot. The lugs will still help guide you to the midfoot but with a softer and more forgiving ride.
What is EMB?
EMB stands for Extended Medial Bridge. This is a feature that you will find on our stability models. The EMB is an area of structural support that extends under the arch to help provide additional architectural support for runners who overpronate. A broader under-foot platform increases ground feel and gives you all the stability you need!
How does EMB work?
The Extended Medial Bridge provides architectural support through greater surface area under the arch to help complement the natural anatomy of your foot. This anatomical support will stabilize your foot without overcorrecting it. Learn more about the specifics of EMB here.
What is heel to toe drop?
Heel to toe drop refers to the measurement between the height of the heel of the shoe and the height of the midfoot. All Newton models have a heel to toe drop ranging from 0-6 mm. This just means that all our shoes are based on a more level to the ground platform to help you achieve a more natural running technique. Learn more about drop here.
Where are Newtons made?
Newton Running is a Boulder, CO based company – all the design, research, and wear testing is done locally in Boulder, and the shoes are produced overseas in our factory in China.
Are your shoes vegan?
Yes! All Newton shoes are made of 100% synthetic, man-made materials.
Are your shoes Thiuram free?
Unfortunatley not. Our shoes are manufactured in a facility which uses thiuram so we cannot guarantee that our shoes are thiuram-free.
Running Form & Other Resources
Good resources and information on Natural Running Form
Newton Running Cofounder Danny Abshire’s book Natural Running is an outstanding resource for people interested in learning more about running efficiency and form. Other resources include:
What should my wear pattern look like?
Newton Running shoes are designed to show wear from the outside-in and your unique wear pattern can give you great feedback about your form and technique. Flip over your shoes and take a look!
Ideally, you should see most of the wear centered on the front third of the lugs under the ball of your foot and little friction wear on the heel or toe of the shoes.
For more information on your wear patterns, check out our customer corner video.
How do I run midfoot downhill?
Running downhill with a midfoot strike takes a bit of time to master. A confident, rapid leg turnover will allow you to stay on the midfoot while continuing to accelerate on the downhill. Keep your feet level to the ground rather than pointing your toes down and stabbing the ground or overstriding and braking with your heel. Watch a demontration here.
Adjusting to the Shoes
Can I rotate my Newtons with my old shoes?
As you transition to your Newtons you can continue to rotate them with your more traditional running shoes. When starting out, we recommend using your Newtons for 10-15 minutes at a time and your other shoes for the rest of the mileage you want to log as this will help you adjust to the more level platform and unique technology in our shoes. You'll notice that the more you're in your Newtons, the less you will want to be in your old shoes!
How long will it take to adjust to my Newtons?
Every runner is a little bit different in how long it will take them to adjust to their Newtons as it depends on a lot of factors - for somer runners it takes a week and for others it may take months. We recommend starting with 10-15 minutes of running in the shoes and building up gradually from there. Click here for more information about the transition.
My calves are sore. Are yours?
Running with a more natural running technique engages the plantar fascia, Achilles tendon and calf with every foot strike. These muscles and tendons work very efficiently in unison but they are tiny and, therefore, susceptible to fatigue. Some slight soreness as you adjust to your Newtons is totally normal and nothing to worry about - it just takes some time to build strength and lengthen those muscles and tendons so be patient and take your time breaking in your shoes.
How far can I run in my Newtons?
Your Newton shoes are built to take whatever distance you want to log in them, whether it's 5 km or 500 km. The only models that are built specifically for shorter distances are our racing flats, the MV3 and Tri Racer.
How many miles will my Newtons last?
All Newton Running shoe models other than the MV3 and Tri Racer have an average lifespan of 350-500 miles (500-800 km). The MV3 and Tri Racer are racing flats with a 150-200 mile lifespan.
If you'don't keep track of your mileage, you can usually tell when you need to retire your current pair based on how they feel - once your Newton shoes are no longer giving you the same "pop" they once were, it is probably time for a new pair.
How do I clean my Newton shoes?
We recommend hand washing your shoes using warm water, a mild detergent, and an old toothbrush. Be sure to remove the insoles first and let the shoes air dry. If you need to replace your insoles simply replace them with an over-the-counter replacement such as Spenco.
