So far I’ve ran a 14k in them, not fair in the grand scheme of things but they were comfortable, they didn’t move around on my feet at all so the sizing was great.
The cushioning on the bottom was nice, it wasn’t too much felt more natural to run in them, rather than to feel like I’m on clouds.
All in all, bit expensive like all running socks but generally worth the money in regards to comfort and good trail running socks.
