Ultralight, Ultra-Focused

For the R135 we switched out the upper of the R1 for an ultralight, breathable, and fast-drying woven mesh fabric engineered for the hot conditions of the Badwater® 135. The result is a shoe that weighs just 7.9 oz / 225 g (US M9), 6% lighter than the original design.

Seen Through the Night

The Badwater® 135 involves running through the night on desert roads. Safety is paramount, so the R135 incorporates a reflective coating on the midsole to enhance visibility for safer racing from dusk till dawn.

Proven to Perform

Underfoot the R135 maintains the tried and true record-breaking formula of the R1: TUNEDFIT Dual Lacing System for on-the-fly fit customization, with dual-zone ZeroSag and LightCELL midsole to boost comfort for the duration of the longest runs.

Be Badwater Ready.

You don’t go to Death Valley for a vacation. You go to prove that you’re worthy of going head to head with the world’s toughest footrace. Each July, the Badwater® 135 creates heroes of the men and women who assemble in Death Valley to run 135 miles across the desert and this year, we have created a special-edition R1 tailored to that unique challenge.

So there I was, casually hopping onto the Mount to Coast website—just minding my own business, looking to replace a beloved, battle-worn pair of R1s—and BOOM. Out of nowhere: the R135 Badwater Edition drops like a meteor of running glory. No warning. No teaser trailer. Just here it is, now try not to scream. Spoiler: I screamed. And then I clicked that order button like it was a race to the checkout line at a Black Friday doorbuster.

And let me tell you something… I snagged these stunners moments before the social media world caught wind. That’s right—beat the algorithm to the punch. That alone should earn me some kind of elite status, right?

Now let’s talk about what actually matters—the run. I laced these beauties up for a weekend long run that could only be described as a heatwave hustle. The kind of day where the sun is trying to boil your toenails off. But the R135? Cooler than a popsicle in a kiddie pool. That lightweight upper? Chef’s kiss. My feet felt breezy, supported, and strangely flattered—like the shoes themselves were saying, “Damn, Steve, look at us go.”

The updated design isn’t just sleek—it’s got attitude. The pops of color, the metallic silver hits? This is race day flash meets long-haul grit. It screams high performance with a wink. And the comfort? Look, I’ve run in a lot of shoes. I’ve broken up with a lot of shoes. But Mount to Coast keeps giving me that “maybe this is the one” feeling. Stable, responsive, with just the right amount of bounce—these shoes make you want to keep going, even when the miles get rude.

Let’s not forget the heritage here. The Badwater name isn’t slapped on lightly—it’s a tribute to endurance, grit, and chasing finish lines that most people can’t even see. The R135 embodies that spirit with every damn step. Whether you’re dodging heat waves or just trying to get through a long grind, these shoes are ready to roll.

Bottom line? The R135 Badwater Edition isn’t just a worthy successor to the R1—it’s a glow-up. A transformation. A shoe that says, “You’ve leveled up. Let’s go show the road what that means.”

On the Steve Scale? Five out of five stars, because anything less would be disrespectful.

GREAT SHOE!!!

I noticed comments saying they just put it on and ran with these shoes. I didn’t believe it but WOW from opening the box to doing my first long run in them in the same day with no pain no blisters just amazing energy and a great feel on the feet. Love these and planning on getting the trail shoes next for my 50 miler ultra in September. Fits very true to size and measurements

Every Mount to Coast model gets better

It's nice to follow shoes that improve with every model, and couldn't be happier with my R135s. Lighter more breathable upper and nice cool colorway. Cheers!

One of the best

Before getting my first pair of R1’s, I debated for several months and I wish I had not waited like that. I wish I had these last year when I did my first 100-mile ultra. For such a young brand to create such a great distance shoe is really amazing. My favorite until now has been the Asics Gel Nimbus for long distance and, in my opinion, the R1 (and R135) are above those. Lighter weight, more durability, a well-made upper, and stellar foam under foot. If I could put the Nimbus knitted and gusetted tongue onto these, they’d be darn near perfect (just my personal preference). I’m looking forward to using the R135 for a 6-hour ultra and 46-mile ultra in August in the Florida heat. My first pair of R1’s took me through 10 hours during a solo fundraising run in June and if I hadn’t been feeling some heat stroke symptoms, they would have taken me to 12 hours of movement. The 2 zone lacing system works great for these type events leaving more than ample room for my swelling feet. I’m really glad I stopped debating and took the leap to get these! On the R135 specifically, I may like the design and color way better than my black and white R1’s!
