They're actually the SL:9 Slalom boots but they've been significantly softened (forward flex and a bit or rear flex give). However, since they're a race boot they are very stiff laterally (good boot if you actually wanna ski as well). They're short-kut so that you have increased mobility in the pipe and for doing grabs etc. They're not the new Tweak boot but they're still AWESOME. Leave me a message especially if you're in Ontario and intersted in a new pair of boots.
