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.
Experience enhanced comfort and control with our signature TUNEDFIT™ Dual Lacing System. Now with two cinch cords per shoe, you can adjust the fit around the forefoot and midfoot independently in seconds. With the adjustable fit, it lets your toes splay, flex, and power through the longest runs in the toughest terrain.
Crafted from a high-performance woven fabric and reinforced with aramid fibers that are five times stronger than steel, the T1’s upper is relentlessly durable. Its anti-siphon knit tongue repels water, ensuring a breathable, fast-drying design that thrives in the harshest conditions.
LightCELL™, our proprietary midsole, is turbocharged through supercritical foaming. LightCELL™ weighs just 50 percent of EVA while offering 45 percent greater energy return – it’s battle-tested by hundreds of ultrarunners for consistent responsiveness, mile after mile.
The T1’s outsole features a trio of Vibram® innovations: Megagrip rubber for tenacious traction in any condition, Litebase for 30 percent less weight without compromising performance, and Traction Lug micro-features for up to 25 percent more grip.
Trail running, elevated.

Customer Reviews
My first venture with this brand. I gotta say, I think they are the best built shoes I have ever had.
The materials are superb, the attention to detail in the build is top notch.
The toe box space is chef kiss.
They are soooo light.
I think they have the best shoe in the market.

Love my M2C T1’s. Been putting them through the wringer on all types of terrain. They are tough as nails but light as a feather. Dual lacing helps the feet so much on those long ultras. Now if they can only get the the Snow Line back in stock (M 10.5)!!
I got these a week or so before my second hundred miler of the year, the Dark Divide 100 in Washington. Technical course with almost 30k vert. The cushioning was awesome, my feet feel pretty good two days after the race. They dry quickly, I didn’t get any skin maceration. The lug design provided great traction. The lacing system is outstanding, I could adjust tightness throughout the race as my feet swelled up. Easy to get on and off to clean out rocks and debris or change socks at aid stations. The material held up well considering the difficult race conditions. I’ll be buying more pairs.
My coach, Scott Jordan, recommended I give these a try. So far, I love them. I had an 18 mile training run on the very technical Pinhoti Trail yesterday and they performed outstanding. I especially appreciate the ability to customize the tightness of the toe box and the uppers. There was a creek crossing about a mile into the run and my T1’s drained and dried quickly. I will definitely be wearing them in the Ga. Jewel 50 miler this year.
When I first put them on they seemed a little clunky. But then when I ran in them. They seemed to propel me forward. I am a bigger runner. 6’1 235. Shoes are hard to find. I went through a lot. These are great! Hands down the most comfortable runner I’ve had .
