Mount to Coast’s 3D Archrail™ is a flexible support structure that significantly reduces peak forefoot abduction angles and activates the abductor hallucis muscle in the arch of your foot. The result is a revolution in stability that helps you to achieve better foot balance for irritation-free running.


Our LightCELL™ compound is a PEBA-hybrid fueled by the industry-leading nitrogen supercritical foaming process. It is eco-friendly and showcases 50% reduced weight and 45% increased energy return compared to traditional EVA midsoles.


Too often stability shoes are heavy and unyielding. Not so the P1. The materials have been chosen to keep weight to a minimum without negatively impacting longevity, and the shoe has been engineered to provide all the stability you need without ever feeling bulky and stiff.


Creates a plush step-in feel with foot-hugging comfort.


Offers quick lockdown with increased support on the midfoot.


Provides exceptional arch support and heel stability you need on the longest runs.

Completed the LA marathon yesterday & was expecting to be marathon Shuffling… not with these bad boys! Just walked my dog 🐩 per usual no pain!!! Love! Them!!!! An absolute must
There aren’t many stability shoes on the market that give you a comfortable run as much as the P1 does. I’ve tried all the brands from HOKA, Brooks, Asics—all have their own key features that make them exceptional. However I found that the P1 checked all the boxes for me. Relatively lightweight, soft ride, stable, and not as traditionally bulky as most stability shoes tend to be. If you’re like me with mild pronation and a lower arch that needs a good stability shoe—I highly recommend the P1. This was my first purchase ever with Mount to Coast and I am nothing but pleased by the quality of their shoes. Worth noting, if you want a firmer feel for a daily trainer, this may not be the shoes for you. My feet are narrow, I’m typically a Men’s 7.5 and decided to go to an 8 to give my feet room during hot summers where I live. But overall, the toe box has ample space and should fit true to size.
This shoe has a lot going for it, but is held back by one unfortunate design decision that significantly impacts comfort - the tongue.
Pros:
- True-to-size fit, very roomy across the toes and forefoot
- Excellent midsole - soft and comfortable, yet supportive with no bottoming out or hot spots
- Supremely stable and lightweight
- Nice materials and appearance
- Durable construction
Cons:
- Tongue is too short, thin, and stiff - this causes lace bite under the knot, and the tongue itself puts pressure on the most sensitive part of the front of my ankle, leading to soreness that lasted all day
- Outsole could have better traction in wet conditions
- Laces are too short (but I do have a high instep)
Overall a great first effort, would love to see a longer and more padded tongue in the next version!
