OK, they may be. Still why the fuck would you buy a boot that doesn't fit your foot? In English, why the fuck would you want to ski in pain because you bought a boot just because it looked steezy?
Now, don't get me wrong, your foot may be a perfect match for the SPK's and I may be wasting my air here. However, I'd give you an 80% chance that this is not the case, which if so, you should go to a good bootfitter and work with him to find a boot that fits you well before even thinking about buying some boot that you think will make you cork 1080's in a day.
