The cross's were a late '08 release. I bought them in late feb as a touring/sledding boot, but I ended up not really using them. I paid $660 CDN for them but am open to offers.
bsl is 306mm. flex is adjustable from 90-120 with the addition or subtraction of a few pieces that stiffen the tongue. Only the krypton pro's come with the different tongue's, but realistically, you wouldn't be changing them all the time. The one thing I really liked about these boots over the pro is they have a 'anti shock' rubber foot bed in them under your liner. takes the bite out of harsh landings. These have heatable liners, but never bothered to do so.
I still have all the extra bits, canting shims, etc. and original box. And like I mentioned, I have only worn these boots a few times. They look like new.
Looking for $250 CDN.
