Other than the color, what is different...
Other than the color, what is different about this boot from previous editions of the Prime? The only thing I can tell by comparing pictures and descriptions is the added dial on the cuff of the liner. What is this for?
The Dial on the cuff is for the BOA system, which the previous boot also had. This years Prime has a wider toebox, other than that I'm not sure.
The liner is supposed to be the most significant difference. It is tweaked to provide better flex in ascent mode. This is according to the BD tech support folks.
Improved liner. Old model was too short. They improved the length...but not by much
