Covering 854 miles (1,374 km) over 17 daily stages, Lucong broke the Asian record for the route, covering more than 600 miles of the journey in a single pair of Mount to Coast S1s.

Details You'll Love
Perfect out of the box, ready to hit the road. They feel incredible.
I bought these shoes to run in but I get so many complements when I use them for daily use that I'm thinking of getting another pair! I did an 8K and my legs did not feel fatigued at all as it had the perfect amount of bounciness. The build quality is great and I would say it's definitely worth the price. It fits snug on the toe box area, but I like it like that.
Ran 5k as a first try and my feet felt so good. Perfect size, super comfortable and easy to walk and run with.
Can’t wait to run more with them
These are by far the best pair of shoes I’ve had that are designed for the purpose of running. They’re super stable, they fit true to size. They absorb so much of the impact while running. It feels like you can find your perfect stride with these and not have to worry a bit about your feet hurting at the end of your runs. Already been raving to my friends about these. 11/10, will buy again.
Went on my first run with my S1's and they felt really nice. I took the chance on these after reading reviews. They have a nice, firm feet. During the run I felt really stable and connected to the ground. They feel like they are going to last forever. Really happy with the purchase so far and looking forward to putting some miles on these!
