I've used these boots for about 2 months now and they are hands down the best boots i've ever owned. They come with a #5 flex tongue that is easily exchanged with a #7 depending on how much flex you want with your boot. I've used these for park and big mountain skiing. I used the #5 flex tongue riding big mountain and was surprised with how well they felt. They were responsive enough for tight turns and bumps while maintaining a bit of flex. For park they are a dream. I haven't had any toe or shin bang and the liners are incredibly warm. My toes were warm in 10 degree weather with normal ski socks. They are really light, which makes hiking and walking a bit easier.
Get fitted and get them heat molded and they will not disappoint you!
