For powder days out here in Colorado I rock these bad girls

They are super stiff for soft boots but I can rage them in the trees (which is all I do on powder days). I could probably put my hardboots on my AM and be just fine but all the bumps, jumps, and terrain would kill my feet by the end of the day, so I opted to just get stiff soft boots.
They're also stiff enough that I can still lay down some trenches when I get to the bottom of the trails and have to cruise the catwalks or take a blue to traverse the mountain. My main limiter of my carving in these is my board (Salamon Maiden) I usually trench it until I fold the nose and then back it off from there.
I have the blessing of midget feet too so no matter my stance I don't get "boot out"
