I've ridden Salomon F20s the past couple of years and absolutely loved them. Then I tried on the new Salomon F4.0s late last year. The new wrap lacing system is an excellent evolution from Salomon's speed lacing.
However I, like you, wanted to go Boa, for both the convenience to adjust on the fly as well as getting the lace as tight as I'd like.
After researching boa focus boots, I ended up recently buying DC Judges. They are as low profile as Salomon's F series, which I like (no moon boots for me please!).
They're relatively stiff like the F22, so I would recommend them. If you want to go Malamute stiff, then move up to the DC Status.
Hey thanks bro, for the info. I'll look into them for sure.
Enjoy your new boots.
