To the two people above me you guys are terribly wrong by saying spks. Spks, are TERRIBLE for steeps. Not because of the flex, because of how it stands you upright. But I will give you a basic idea of boots to try on for steeps.
Salomon(in general wide)
any of the falcon seiries for stiffer (especially pro/race)
Ghost is also decently stiff(haven't heard much about it though)
Gun(midflex, good all around)
Foil(as soft as spks, just doesn't have the upright stance, good all around if you lilke it soft.)
Anything Full TIlt, just they are super narrow.
Dalbello Kryptons are also pretty narrow.
Technica
diablo is mid flex and great all mountain, I think it is mid-width too.
Agent 100 or 120 is a good all around boot that you can choose the flex on. Mid width.
Lange freeride 110 is a mid width that is slightly on the narrow side.
But, go in and tell the shop guys what you want and they will bring out like 10 boots to try on that will be great for you.
