I currently have salomon x10s but they're getting near their EOL...I was looking at fulltilts cuz everyone seems to like them, but it seems like a phase to me...It just doesn't seem like it would be supprtive enough for hard carves and stuff...I understand that Seth rides them, but I think he could do it in flip flops...are their mid flex boots stiff enough to get by with all mountain and still be okay in the park?
