I bought a pair Tree Runner 1 because of the good reviews here and recommendations through word of mouth. I was initially impressed by the durability, especially after dragging them through a spring skiing trip in Austria. Quite unbelievable that they became white again. The shoe is comfy enough, maybe a little firm for my liking.
One super annoying thing is that something happened to the sole causing it to absorb water and make squeaks with every step. What is even more strange is that the inside of the shoe stays dry despite this. In the rainy danish climate this would have been a deal breaker for me if I had known up front. (See the video for the squeak, sound on 🔊)
All in all a decent shoe, but not for wet climates
