Size Measuring Guide
A perfect fit for your ultra-marathon running shoes is important for comfort and performance. Follow these tips to measure your foot size at home:
General Tips:
- Measure your feet at the end of the day as they're at their largest due to swelling.
- In between sizes? One foot is bigger than the other? Take the larger size.
- It's best to measure every year. Your size could change over time.
What You'll Need:
- A piece of paper larger than your foot,
- A pen or pencil,
- A ruler or measuring tape,
- Socks of the thickness you'll wear with the shoes.
Steps:
- Stand on the paper in the socks you'll wear with the shoes.
- Use the pen or pencil to mark the end of your longest toe and the back of your heel. It's important to measure both feet as their size can vary.
- Match your measurements to our size chart to find the best fit. If you're between sizes, we suggest choosing the larger size for better comfort.

The proof is in the eating.
Adventure and athleticism take many forms. In January 2025, ultrarunner and race director Jamil Coury toed the line for a chance to win a year's supply of free burritos. The challenge: run as many miles as possible outside an Arizona restaurant. What followed was an absurd commitment to athleticism and competition that saw him run more than 730 miles. And his shoe of choice for over 600 of those miles? A single pair of the new Mount to Coast H1s.
Featured
Created through a process of advanced supercritical foaming, each pair of CircleCELL™ midsoles is made from up to 20 pounds (9 kilograms) of organic waste and residual biomass. Despite its sustainability credentials, CircleCELL™ delivers energy return on par with PEBA, with almost double PEBA's running lifespan.
Mount to Coast VersaGrip™ is engineered to deliver exceptional traction, confidence and durability across all terrain, so you can run to the trails from your front door without ever missing a step. Worried that a road shoe will be out of its depth on the trails? VersaGrip™ has got your back. This is optimal performance for real-world situations.
The TUNEDFIT™ Dual Lacing System offers separately customizable fit for the forefoot and midfoot. Because we know that in the ultrarunner’s pursuit of distance, feet can swell and change shape, and having a shoe that can adapt to those changes on the fly can be the difference between minor discomfort and injury.
The H1 features a dual-zone upper. Across the top portion, the shoe is engineered with jacquard for adaptive fit and comfort, while the lower part is crafted for exceptional durability with a high-performance woven fabric, reinforced with aramid fibers that are five times stronger than steel.

My first love was the pearl Izumi N2. Ran 5ks to 100 milers in that shoe. When it was discontinued I lost a dear friend and training partner and have been searching for a replacement shoe ever since. Cut to 2026… I’m older, realized that im a little less resilient, and need to take care of my body. The H1 has gobs of cushion, enough support to make me feel like I can still get out there and push myself, all with enough good looks that my wife doesn’t roll her eyes every time she sees me in my running kit. Thanks Mount to Coast, for making a shoe that makes running fun again.
This is my second pair of H1s.
The first pair started with < 10 mile break-in and then the entire Javelina 100M with zero foot issues. Still using those shoes in training, but wanted a backup pair for a race at the end of June in Northern California.
Love these shoes and was looking to rotate them with the La Sportiva Prodigio Pro but because of lace bite on them, I decided to stick with these for my 50k training. No regrets!
Snug, supported fit throughout my entire 50k race with no relacing or discomfort! 33 miles through mud, roadways, streams, gravel and dirt trails...never needed adjusting even once!
118 miles on these in 1.5 months and still bouncy with plenty grip.
Best shoe ive worn yet. My only choice for trail running. Looks great AND soft enough to be comfortable, but firm enough to feel springy. 50k in 2 months. Let's get it!
Love these. Put 35 miles on these the first weekend over a combo of road, treadmill, and smooth trail and they were excellent on all. Fit was similar to R1 with a little more cush, but still very responsive. Ordering another pair!
