Reviews Running Mount To Coast

Mount To Coast M1 review: big cushion, big energy, no plate needed

The Mount To Coast M1 pairs bouncy JETCELL foam with Vibram Megagrip grip for ultras and long trail days. Here's how it performs and who it's for.

Trail supershoes with carbon plates keep getting more expensive, more specialized, and more demanding to run in. The Mount To Coast M1 takes a different path: put the bounciest foam the brand has ever made in a high-stack, plateless package, and let the ride do the talking.

The M1 is a cushioned all-mountain trail shoe built for long, mixed mountain days, ultra-distance efforts, and the kind of trails most of us actually run. The headline is JETCELL, a new supercritical foam with energy return closer to a road supershoe than a typical cushioned trail shoe.

Wrap it in full-coverage Vibram Megagrip and Mount To Coast's clever dual-zone lacing, and you have one of the most compelling long-distance trail shoes of the year at $195.

And it comes with serious backing: Rémy Brassac recently won UTMB TDS 2026, nearly 150km with over 9,000m of climbing, wearing this shoe.

Sizing and fit

The M1 fits true to size for most feet, but if you're on the top end of your usual size or have high-volume feet, go a half size up, especially for long efforts where feet swell.

That's the brand's own guidance and it's worth following.

The toe box is roomy enough for natural splay, the heel cup is secure, and the upper is more structured than the brand's road-to-trail H1, which pays off in lockdown on uneven ground.

The TUNEDFIT dual-zone lacing takes one run to learn: dial the forefoot zone once, leave it alone, and only adjust the midfoot between runs. A new elastic lace keeper tucks everything away neatly.

Features I love

The JETCELL foam feels genuinely special

Every conversation about this shoe starts with the foam, and rightly so. JETCELL is built with supercritical foaming from automotive-grade materials, and the brand claims twice the structural strength of standard PEBA.

On the trail that translates to a soft, forgiving ride that never goes squishy or unstable, unless you hit the challenging terrain. It's not a trampoline; it's a smooth, efficient pop with a clear squish-and-release that gains structure as it compresses.

More than once I've glanced at my watch expecting cruise pace and found myself running noticeably quicker. Crucially, it's built to feel the same at mile 8 and mile 80, which is exactly what you want from an ultra running shoe.

It's made for long days on your feet

The M1 lives its best life on graded singletrack, fire roads, gravel-to-trail link-ups, and rolling mountain days measured in hours.

The moderate rocker rolls you forward smoothly, the 38mm stack keeps you protected above the trail, and there's enough pop to open up on runnable descents with no penalty at easy pace.

At 9.3oz with this much foam and full Vibram coverage, it never feels like a max-cushion brick.

The racing pedigree backs the design up too: beyond that UTMB TDS win, a prototype carried a 29-hour improvement on the women's Triple Crown of 200s record, plus an 8th place at Western States this June.

The Vibram Megagrip outsole is never the weak link

The 4mm lugs bite confidently on loose dirt, sandstone, wet rock, roots, and slabs, while the Litebase construction keeps weight down and behaves well on harder surfaces, so fire roads and short pavement connectors are prime territory.

Dirt packing is minor and taps out easily. If you want the deeper story on why this rubber shows up on so many great trail shoes, our Vibram Megagrip explainer covers it.

The upper is built for hot, wet, long efforts

Breathability is outstanding, the upper drains quickly after creek crossings, and the TPEE yarns dry fast.

Add the gaiter attachment points and that secure, structured hold, and this is a shoe you can trust deep into a long day without hot spots or soggy-foot misery.

What could be improved

Stability on genuinely technical terrain is the real conversation.

A 38mm stack of energetic foam has physics to answer to, and on relentless off-camber rubble or steep, chaotic descents, a lower, firmer shoe is the better tool.

The wider platform and raised sidewalls keep it perfectly adequate for most runners on most trails, but if your weekends are all ankle-breaking chaos, the lower, firmer Mount To Coast T1 is the smarter pick in the same family, and it saves you $15.

Deep winter bog and gluey mud are also beyond what 4mm lugs can handle, and there's no true wide option.

My verdict

The Mount To Coast M1 is a cushioned all-mountain cruiser with genuinely special energy return, dependable Vibram Megagrip traction, and long-day comfort that holds up.

Judged on that brief, it does its job better than almost anything in the category, and at $195 it undercuts most plated trail supershoes while making a strong case that you don't need a plate at all.

If you want one cushioned trail shoe for ultras, long mountain days, and the majority of singletrack, this is it.

Shop the new M1

Within the category, the Saucony Xodus Ultra 4 remains the more affordable all-rounder at $160, and the On Cloudultra Pro is the pricier, racier alternative. It also sits in the same neighborhood as the Hoka Speedgoat 7, with a livelier foam and a cleaner look.

For the full field, our best trail running shoes roundup covers every category.

Within Mount To Coast's own lineup, the M1 is the plush, high-energy trail sibling to the T1, while the Mount To Coast H1 remains the door-to-trail pick when your routes need less traction.
