I bought the Cirro's last year as my first pair of boa boots. After trying a few others at the shop and at the mountain, I narrowed down my choice to these. These boots, they just freaking ROCK! As most boa boots have only one boa on the top at the front, these are the dual-zone boa's...The customization of your ride is a feature I couldn't have been more pleased with. If you want your foot to be a little more snug to your binding and board, tighten up the boa on the right. If you want your legs to be a little tighter so you can lock in those quick turns without the wiggle-wobble, tighten the front. Of course the convenience of not dealing with laces, which is the whole POINT of a boa boot, is awesome. No more sitting at the top of the run, getting ready...Lacing up the boot and tying it JUST right so you have just enough pressure to be comfortable, but not TOO tight. Now, there's no need to worry. Too tight for the boa? Then just pop the knob out as the wire unravels, then push it back in and wind it back up. I could NOT be happier with these boots. DEFINITELY worth every cent.
