there are soooo many better boots than that. I rode them for 2 years and I thought they were the shit but then I got some Dalbello Krypton Rampages and they are soo much better. My heel is locked in and they are stiff.
with the 1080s (foil) everytime I landed switch on something bigger than 6 feet, my heel would lift up and it would hurt like a bitch. And they were waaay too soft. Stiffer boots are better cause you get more response and all the flex and whatnot goes into the ski, not your boots. This means that when you lean foward, instead of your boots flexing, your skis will flex, and you will do a nose butter.
the 1080s also were bunk for butters. my heel always came up. If you want a good boot then you should look into the SPK, Head Mojo, or Dalbello Krypton Rampages.
