BOA Boot?
K2 & Vans make them.
IMO they are alright, I personally like having control over my upper and lower region. So I still rock the laces, but there is the burton system that is pretty quick as well. Also it holds very tight.
But back to the boa. There is 2 types I believe. The regular that is common on most boots, then there is the Coiler. It looks like a 3 spoke rim. That automatically winds up the slack so you aren’t spinning the knob to wind in the excess.
It’s tight, consistent, and easy to use.
Comfort wise… well it all depends on the comfort of the liner and boot itself.
