The Mach X 2 features the same Pebax® plate as the original low-top, but the added midsole foam creates a springier ride. And it’s not just any midsole foam–it’s an additional five millimeters of PEBA foam, an ultra-light foam commonly used in high-performance shoes.
This thick stack of PEBA foam acts as the top layer of the midsole, while the bottom layer is a more traditional EVA foam. The two layers are separated by the Pebax® plate, which compresses as you land and flexes as you take off. The result? A lightweight, energetic feel suitable for speed work and races.
“I really enjoyed the underfoot feel and ride of the Mach X 2,” says Travis who, in addition to being a super fast runner, currently has a lead role in a local production of “Rent.” “The shoe offers great ground contact and a smooth transition with the meta-rocker. It’s not a soft or cushy shoe, but it has a lot of energy that made me feel like I was just hopeful. I’m not in great shape right now due to the show I’m in, but my pace in the Mach X 2 made me feel like I was in better shape than I thought.”
I’m in the same boat as Travis (although I don’t have a starring role in “Rent”). I’m not in my best shape right now due to an ankle injury forcing me to decrease my volume. I took the Mach X 2 out for a spin during a fartlek run. The shoes felt pretty firm and peppy as I began my warm up and did my strides. Once I got into the workout, though, I completely forgot about the shoes and was only focused on trying to hit my paces and not pass out in the humidity. It was a success, and the shoes probably helped!
“The foam in the Mach X 2 feels thick and bouncy,” says Kate. “It compresses slightly upon landing, then immediately snaps back for a really lively and fun running experience. It makes me feel like I have more energy, which is an amazing feeling.”
The shoe is rounded out with what HOKA calls a “sticky rubber outsole.” It’s only placed on the forefoot and the lateral and medial sides of the heel to maximize weight savings. I don’t think it feels sticky per se, but when I run my finger across it, it definitely doesn’t feel smooth.
The “stickiness” translates to better grip on the road. Kate definitely noticed a difference.
“I was running on a wet day when I tested the Mach X 2. I still have my pair of the original Mach X, so I changed into the Mach X for the last two miles to get a head to head comparison. Once I changed, the road felt more slippery.”
I did my intervals in a park where I was Kaha to make some tight turns, and I felt really confident in my footing.
Not only does that confidence speak to the outsole traction but the stability of the entire shoe. Keep in mind that the Mach X 2 has a heel stack height of 42 millimeters (44 for the men’s model), so easily taking tight turns isn't a given. Perhaps the Mach X 2’s firmness creates the stability needed to run in a high-stack shoe with confidence.
