New Balance MT100-WT100 Review

Designed with the help of Anton Krupicka and the Skaggs brothers, there aren’t a lot of extras on these shoes. Watch the following video for a closer look at this lightweight, trail-worthy shoe. As with future video reviews on iRunFar, you can also skip ahead to written summary of the video review.

New Balance MT100/WT100 Review
The New Balance MT100/WT100 (hereinafter MT100 for simplicity’s sake) is an evolution of the New Balance 790. It’s a marquee shoe in the current set of low profile trail shoes. A men’s size 9 tips the scale at a mere 7 ounces and change. Be aware that you’re wallet will weigh more than after buying most other trail shoes as the MSRP is a mere $75. For the over eager, iRunFar has previously shared a sneak peak at the MT101/WT101 due out late in 2010. Below, we’ll look at the shoe’s outsole, midsole, and upper.

The MT100’s outsole is trail specific, but is suitable for some road running. The shoe is particular adept on packed dirt. It is not the shoe of choice for sloppy mud.

New Balance MT100 outsole

The New Balance MT100's lightweight, trail-worthy outsole.

The foremost half of the outsole features lugs a few millimeters thick. Minimally textured rubber stretches from the arch back to the heel, which is home to the shoe’s most significant lugs for braking. The outsole features circular cutouts that reduce weight.

The MT100 has a single density midsole, meaning that the shoe does not have a post for pronation control. On the other hand, the midsole is raised on both the inside and outside of the midfoot. This results in a fair amount of support for the shoe’s weight.

New Balance MT100 midsole

The New Balance MT100's surprisingly supportive midsole.

The Rock Stop rockplate sandwiched between the outsole and midsole offers decent push-through protection in the forefoot and midfoot. The TPU plate does, however, mean that the shoe is a bit stiffer in the forefoot than some comparable models and creates a pivot point at the rear of the rockplate.

The upper is primarily mesh backed by lightweight fabric and has minimal overlays. These combine to provide a sock like feel that gives the foot room to wiggle around. However, the upper also does not offer much lateral support, which can be problematic on technical or switchbacking trail. The highly breathable fabric allows water to quickly drain from the shoe.

New Balance MT100 upper

The New Balance MT100's highly flexible upper.

The ankle collar and heel counter are made of a material akin to nerf foam. Unlike conventional shoes, there is no fabric covering the foam on the shoe’s exterior. Some users, including iRunFar’s Bryon Powell, have had the hard foam at the top of the Achilles notch slice into the skin covering the Achilles while running sockless. Other runners have experienced similar discomfort while wearing socks. If needed, the upper portion of the Achilles notch can be cut away. New Balance is aware of the problem and is addressing it in the MT101.

The MT100 also has a minimal tongue consisting of a single layer of the lightweight mesh/fabric combination that makes up much of the shoe. The “sausage like” Sure Laces keep the shoe secure and laces locked tight.

    I love love love these shoes! I've worn them on everything from dirt to rocks to roots to snow to scree and even some pavement. The rock plate is amazing. I can still feel the ground, but nothing pointy or painful–exactly what I want in a minimal shoe.

  2. MikeC

    I have a pair of these. Bought them after nearly getting frostbitten toes trying to run in the winter with Five Fingers shoes. Love these shoes. They aren't as low to the ground as the Vasque transistor, but feel much lighter. The laces are GREAT, such a small thing that I really like. Mine are starting to smell, would love a new pair!

    I have never worn a "minimalist"trail running shoe. My current trail shoe is Brooks Cascadia. I like it because it is very flexible for a variety of terrain and provides good protection. Come to think about, based on the NB MT/WT100 review by Travis, it sounds like Cascadia and MT100 have many similarities with the latter being a much lighther shoe

    Hey Bryon,
    Great to see you hooking up with Travis on the reviews. His webisodes/reviews are always informative. Another great addition to irunfar.
    I have been wanting to try the MT100's since I am moving towards more minimalist shoes. Thanks again for a great site. Be back tomorrow, just like every other day!

    Have found these shoes to be one of my favorite go-to runners for up to 40 milers for all trails but the most muddy, gnarsty conditions. I wear mine with lightweight socks. Very natural trail feel and the rock plate rocks.

    What sizes do you have available? New Balance is almost completely out of stock (online), as are most other retailers. I just ordered a 13 in the hope that it won't be too big, but I'm pessimistic.

      I was not been made aware of any size restrictions when I checked in with NB a week or so ago. As for sizing, the shoes are the "correct" or standard size when worn sockless or with thin socks. You could always sock up if need be.

    great review yet again. i've been wanting to take these for a spin since i learned about them last year. they seem ideally suited to the typical shoe and style of running i love.

    Gettysburg, PA. After reading an early post on irunfar about the NB100, I decided to give them a try. They are sock-like compared to my other road shoes (NB and Brooks) and trail shoes (Brooks) and feel great. I worry a tad about covering rocky terrain in them, so I've stuck to more 'manicured' trails. They've worked well for me. I'd love a new pair.

    I would love to try a pair. I've been looking all over for a pair in my size. I can't find them anywhere. Very limited size selection.

    Does anyone know why these shoes are so hard to find, or where I can find some?

    Thanks from Braselton, GA

    I bought my Suunto T6c on the back of a review you did and I couldn't be happier. I'll definitely be subscribing to your reviews Travis. Thanks!

    How is toe protection with the MT100?

    I'm interested in trying these shoes, as I've been hearing great things about them, just as I had been hearing great things about their predecessors.

  12. Colleen, Linden, VA

    I've worn the NB 904s and loved them so I am very interested to see how these shoes compare. Would love to be able to try them out.

    I would love to try a pair of these out on the rocky trails up here in the Northeast … keeping my fingers crossed.
