Customer Reviews
It took about 30 miles to break in but I’m a believer. Was able to push 7 min miles in these comfortably for 10 miles. Great feel to these shoes. If you’re on the fence go for it
Got my S1’s early this week and so far have done 2 runs, a 3 and 6 mile run. They fit just right and it almost feels like the shoes become one with my feet! Impact with the ground is soft but yet great stability. I have a 12-15 mile run this weekend so looking forward to see how it does! Excited!
I bought the S1 model and ran in it for the first time today. Just a short run to try it out and right out of the box, they felt very comfy, lots of room in the toe box and just enough spring, but not too bouncy. I can't wait to run a longer run in these great shoes.
I’m seriously impressed with this shoes! They have good cushion and yet don't feel too plushy and still feel responsive (which I think a lot of other shoes that offer thick cushion are lacking!) and they are very comfortable. I can’t wait to log a lot of miles in them and try the R1.
Wow! Been running in my pair of S1's for a couple of weeks. Absolutely love them! Most of my miles are road miles so Mount to Coast is perfect. Planning on running a road 100 miler in December and Mount to Coast will be the shoe! S1 or R1. Look forward to purchasing the R1 soon!
S1gned, Sealed, Delivered
In the spring of 2024, Asian ultrarunner Lucong Geng traveled to Scotland to run the JOGLE, a multistage road ultra to the most southerly tip of England. 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.
