It's really good shoe, grip is nice, and very comfortable, and very safe.
I used it for Kalsubai (Maharashtra) and Hampta pass (Manali).
It's water proof, water did not enter from sides, only way is from top for that u avoid entering water from top specially crossing river/nalla.
While crossing Hampta pass at top I could felt cold inside shoes, for me u can't walk on snow for many Ours unless, it depends how much cold you can bear, I spent 2 to 3 hrs.
I got this shoe for my daughter,s activity week. She was happy with it and said it was comfortable. She did say it might have been better if it had a higher ankle support
