Replying to FULL TILT B&E BOOTS FOR FREERIDE

I have worn the dalbello boss boots for the past couple years which are great for my wide ass feet and serve me well all over the mountain and in powder. Issue is they got stolen from my local dome a couple weeks back along with a jacket which i am not too bothered about but the boots and liners are gonna be expensive to replace. My buddy has had a knee op recently and has kindly said i can use his b and e boot until i can afford to replace my own. They fit good and are nice and light but i am not sure how they will hold up in the deep stuff. Has anyone had any experience with them for anything other than park which is obviously what the design of the boot was made for...??

many thanks
