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.
We expect the MV3 to debut mid-Summer, 2013.
We can help you right here.
Please use the ShoeFitr application (located on each shoe page) in order to help with an accurate size estimate.
The ideal fit with Newton shoes is with the bones of the ball of your feet directly over the center of the raised lugs on the outsole of the shoes.
This alignment typically offers a thumb's distance of space in front of the longest toe to the end of the shoes.
Universal posting is the denser, more-supportive midsole foam located along the medial (inside) and lateral (outside) edges of our shoes. This runs from just forward of the heel to the ball of the foot, and reduces pronation and supination. Pronation/supination is the foot's propensity to roll in or out as you load your foot.
Because of its posting on both the medial and lateral sides, Universal posting also accommodates a neutral gait type.
Yes. Simply remove the sock liner that comes stock in the shoes, and replace it with your over-the-counter or custom insole.

Yes, the Sir Isaac Wide Guidance Trainer accommodates a 2E width foot.
It is unlikely you are too heavy for Newton Running Shoes. The technology used in all Newton Running shoes works like a trampoline – when your foot strikes the ground, the raised lugs on the outsole compress through a stretch membrane into a hollow chamber in the midsole. Since when were you too heavy for a trampoline?
If you are currently running with a heavier heel strike, we encourage you to modify your gait to a more natural running stride. In this case, you may find our Guidance Trainers (M/W) the best in terms of fit and function.
Newton Running shoes are designed to show wear from the outside-in. It’s one of the most helpful bits about our shoes, and your unique wear pattern can teach you a lot about how you’re running.
Ideal wear on your Newtons is with friction accumulation on the front third of the raised lugs under the ball of the foot, and the rear two-thirds showing less wear. Friction wear in front of the raised lugs represents excessive toe-off; efficiency can be gained by focusing on lifting from the hip flexor at the end of the stride rather than pushing off from the toe. Mild friction wear on the heel is nothing to be alarmed about.
All Newton Running shoe models other than the MV2 have a lifespan of 350-500 miles (500-800 km). The MV2 is a racing flat with a 150-200 mile lifespan.
If you've not tracked your mileage, you can base your need for new Newton Running shoes on how they feel – when you feel like your Newton shoes are no longer giving you the same "pop" they once were, it's time for a replacement.
The best way to clean Newtons is by hand. The shoes are not designed to tolerate the agitation and extreme conditions of a washer/dryer. We recommend scrubbing them in the sink, using a mild detergent and an old toothbrush. The insoles should also be cleaned by hand, or if they get past the point of cleaning, simply replace them with an over the counter insole replacement such as Spenco.
Newton Running is a Boulder, CO based company – all the design, research, and wear testing is done here locally, but our shoes are produced overseas in our factories in Indonesia and China.
We recommend that a runner new to Newtons continue to switch back and forth with their traditional running shoes as they're adjusting to the level platform and peppy technology in our shoes. Use your Newtons for 15-20 minutes at a time at first, and your other shoes for the rest of the mileage you want to log. You'll notice that the more you're in your Newtons, the less you want to be in your traditional shoes!
Running with a midfoot strike engages the Plantar fascia, Achilles tendon and calf with every foot strike. The muscle/tendons work very efficiently as a trilogy, but they're tiny, and therefore susceptible to fatigue. Couple your new midfoot strike with a propulsive Newton shoe, and you might find that you're a little sore.
This is totally normal and nothing to worry about - it just takes some time to build strength and lengthen those muscles and tendons. Have patience and add time in the shoes in small increments.
Everyone's a little different with how they adjust to their Newtons; some take a week, and others take months. Start with runs of 15-20 minutes, while continuing to log the bulk of your mileage in your traditional running shoes. The best advice is not to do too much too soon; be deliberate with your time in the shoes, and cognizant of how you feel as you go.

Definitely. Your Newton shoes are built to take whatever distance you want to log on them, whether it's 5 km or 500 km. The only model that's built for short distances specifically is the MV2.
As you're adapting to your Newtons, we do recommend that you switch back and forth with your traditional shoes. Once there, Newton Running shoes are designed to be your full-time training and racing shoes.
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.
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:
The MV2 is a "zero-drop" shoe engineered for athletes who practice Newton running form. The MV2 is unique in that it is built on a level profile: There is no drop from the heel to the midfoot, hence the term “zero drop.”
It is not unusual for runners who are transitioning to a zero-drop shoe like The MV2 to experience tightness in their calf muscles and Achilles tendons, as well as their feet. This can occur because the muscles and tendons are further elongated when running in a zero-drop shoe, compared to a conventional shoe with a lifted heel.
Adapting to a zero-drop shoe and a Newton running style takes time, and the process is unique for each athlete. It is always better to make this transition gradually. With this in mind, we enclose a removable 3 mm heel lift with each pair of our MV2 models in the event that you wish to transition with incremental steps. This is particularly recommended if you are transitioning from a shoe with a high heel-toe drop.
The MV2 runs a bit more snug than other Newton shoes, so most runners size up a 1/2 size larger than their traditional Newton shoe size.
Built as a racing flat, the MV2's lifespan is 150-200 miles.
The MV2 is meant for tempo runs, interval sessions, and 5k/10k racing.
As most running shoes have a heel to toe drop, it can be challenging to adapt to the totally level platform of the MV2. Starting out with the 3mm heel lift offers you the opportunity to gradually elongate the lower leg and foot muscles/tendons. Once acclimated to the 3mm drop, you can remove the heel lift if you'd like.
The MV2 provides much greater longevity than typical racing flats if you are running efficiently. As with all of our shoes, the MV2 wears like car tires – you will begin to see wear externally on the lugs almost immediately. It’s time for a new pair when you feel like your MV2s are no longer giving you the same "pop" they once were.
The membrane is lightweight and tuned to react faster, promoting higher cadence. The lower-profile design includes five articulating lugs.
Anyone can run in the MV2. As the MV2 is meant for tempo runs, and 5k/10k racing, it's best kept as an "addition to" rather than an "instead of" shoe in your Newton collection.
The MV2 is meant for shorter, quicker training runs, and 5k/10k racing. If you're looking to run longer distances, we recommend our other Performance shoes.
The shoes are nimble and offer great traction. They can be used on paths and dirt roads, but MV2 was not designed for rugged terrain. The uppers are not designed to provide lateral support and there is no protection for hitting hard objects like rocks and roots.
