Mountain to Coast T1 – Faye Johnson’s Test
Introduction
As trail and ultra runners, we scrutinise everything, our nutrition, our training load, our pack weight, yet the single most important piece of kit we make is the shoe on our foot. Get that wrong and nothing else matters. Get it right and you’ve got a platform to run confidently across whatever terrain the trail throws at you.
I’ve been testing the Mount to Coast T1, the brand’s debut trail shoe, over a sustained period that has included regular training runs across a variety of terrains and, crucially, a recent 50km ultra. The result? A shoe I have genuinely loved wearing.
Features
- Drop: 4 mm (stack height: 36 mm heel / 32 mm forefoot)
- Weight: 255 g (US Men’s 9)
- Midsole: LightCELL™ — supercritical PEBA foam for lightweight energy return
- Outsole: Vibram® Megagrip with Litebase and Traction Lug micro-features
- Upper: High-performance woven fabric reinforced with aramid (Kevlar) fibres
- Lacing: TUNEDFIT™ Dual Lacing System — two independent cinch cords for forefoot and midfoot
- Additional details: Anti-siphon knit tongue, lace garage, wider toe box design
- RRP: £170 at Mount to Coast
Mount to Coast have come to the trail shoe market with clear intent. The T1 has won an ISPO Award in 2024 and carries an APMA Seal of Acceptance, both indicators that the detail work here is serious.
Fit & Comfort
For runners with a narrower heel and broader forefoot – which describes my own anatomy – finding a shoe that accommodates both ends of the foot without compromise is genuinely difficult. The T1’s wider toe box is a real win here, and when you pair that with the TUNEDFIT™ dual lacing system, the result is something close to a bespoke fit. Being able to independently adjust the tension across the forefoot and midfoot is brilliant – it’s the closest I’ve come to the simplicity and effectiveness of the Salomon Quicklace system, and in some respects it surpasses it by giving you that zonal control.
The shoe did feel slightly stiff on first wear, particularly from an upper perspective, but this settled quickly and within a very short period it felt broken in and comfortable. It is worth noting this, however, for runners who are sensitive to that initial rigidity.
On sizing, I went for a 41 on their chart, translating to a UK 7, and this aligned exactly with my usual size. I would say go with your normal size, but if you typically sit on the cusp between two sizes, go up.
Performance
This is where the T1 really earns its place. I have tested it across open fell, hard-packed trails, single track, and proper British wet mud and it has stood up well to all of it. The Vibram Megagrip outsole is excellent; it inspires confidence across surfaces that would expose a lesser shoe.
The cushioning sits at exactly the right level for me. I have historically preferred a lower-stack shoe, but over the last couple of years I’ve recognised I need a little more underfoot protection, particularly over longer distances. The T1 hits that sweet spot, enough cushion to protect the foot over a 50km effort without killing ground feel.
The 4 mm drop is another sweet spot. It’s a position I return to again and again for longer distances, and this shoe manages to feel both like a solid training tool and a genuine race-day option. The lightweight construction enhances that versatility further, this does not feel like a shoe you are carrying around the course.
Features like the lace garage keep things tidy and practical during racing, and the overall build quality – Kevlar-reinforced upper included – suggests genuine durability over serious mileage.
Pros
- Wider toe box suits runners with a broader forefoot
- TUNEDFIT™ dual lacing gives a genuinely bespoke, secure fit
- Cushioning level offers ground feel without sacrificing protection over distance
- 4 mm drop is a versatile and comfortable position for training and racing
- Vibram Megagrip outsole performs well across fell, trail, single track and wet mud
- Lightweight and well-featured – lace garage and dual cinch system are excellent details
- Sizing runs true – go with your normal size
Cons
- Upper can feel slightly stiff on first wear – this does ease quickly
- Price point is premium, though in my view a versatile shoe built for this kind of mileage justifies the investment
Conclusion
The Mount to Coast T1 is a versatile, well-engineered trail shoe that performs above expectations across a wide range of conditions and distances. For runners navigating the challenge of training and racing in a single shoe, and who need to accommodate varied foot anatomy, it offers a level of adaptability that is genuinely impressive. I ran a 50km ultra in these and came away wanting to lace them up again. That tells you everything you need to know.

Mount to Coast T1 – Luke Jackson
Big thanks again to Katie Allen at RunUltra for introducing me to the Mount to Coast T1, a brand I knew nothing about before this. After a solid month of testing, I’ve put these through their paces properly.
The standout test? A marathon effort around Kielder Forest, running alongside my mum on her first ever marathon. Unreal experience and the perfect environment to see what these shoes are made of.
First off, the look. These are a seriously good-looking shoe. Clean, modern, and something you’re happy to lace up day after day.
The dual pull-cord lace system (split between upper and lower foot) caught my attention early. I wasn’t sure at first, I thought the thin cords might dig in, but in reality, they’re spot on. Once set, they’re secure, comfortable, and caused zero issues across long miles.
Grip-wise, I’ll be honest, I underestimated them. Coming from a fell background, I’m used to aggressive lugs, and these didn’t scream confidence out the box. But out on the trail and even on slippy northern fells terrain they really held their own. Descending in mixed conditions, I felt far more confident than expected.
Underfoot, the Vibram sole feels solid and dependable, and pairs really well with what is easily one of the standout features of this shoe, comfort.
This is where the T1 excels. Cushioning is exceptional. These are built for long days, big miles, back-to-back efforts, time on feet. You put them on, forget about them, and your feet feel just as good at the end as they did at the start.
Durability so far has been seriously impressive. I’ve put decent miles into these across road, trail, and fell, and there’s virtually no sign of wear, just a bit of mud. The outsole still looks solid, the upper’s holding strong, and they feel like they’ve got plenty left in the tank. Early signs suggest these will go the distance.
Terrain sweet spot?
These are right at home on:
- Forest trails
- Well-made paths
- Riverside tracks
- Mixed terrain with some mud and variation
Kielder Forest was pretty much the perfect playground for them, they felt effortless out there.
They’ll also handle road sections and lighter fell without hesitation, which makes them a great “do-it-all” option. If anything, for a long day out in the hills where comfort is key, I’d happily reach for these.
What are they not for?
If you’re racing hard on technical fell terrain, bogs, loose rock, steep descents and really pushing the limits, you might want something more aggressive, more precise, more locked-in.
For me, that comes down to feel. I like a tight, snug, aggressive shoe when I’m in that mindset, it’s almost ritualistic. It puts me in the zone to really send it.
That said, this isn’t a flaw in the shoe. It’s my preference.
Final Thoughts
As an everyday training shoe, the Mount to Coast T1 is outstanding. Comfortable, versatile, durable, and far more capable across terrain than it first appears.
If your weeks are filled with long runs, mixed terrain, and time on your feet, you’ll struggle to find something that does it much better.
This one’s earned its place in my rotation.
Fully recommend.
Score Breakdown
- Design: 10/10
Unreal looking shoe. Clean, modern, and something you want to wear every day. - Features: 7/10
The dual lace system feels unusual at first, but works well in practice. Solid, functional features that do the job. - Value: 7/10
At £170, they’re not cheap, but they deliver. Durable, comfortable, and capable across multiple terrains. You get what you pay for. - Performance: 8.5/10
Not a race-day weapon, but that’s not what they’re built for. As a long-run, high-mileage training shoe, they perform exceptionally well and are hard to fault.
