Pros: Instep strap, quick lacing, very comfy after 2 week break in period
Cons: High volume, a bit too soft, not the most waterproof, non-zonal lacing
I've been a fan of Salomon boots for a while, and have ridden F22s for years. This year the F22s were replaced by the F3.0s, and as I needed new boots, I bought them. The boots use a new wrap lace system which is quick, but not the easiest to dial in a precise fit since it only uses a single lace. The wide strap over the instep is ingenious, as it allows you to tighten the boot and really secure your ankle without cutting into it as with BOAs or many other lacing systems.
For being an F-series, the boot was pretty high volume. It was unnoticeably smaller than any other boot but has the huge deficit of the non-removeable liner. This coupled with the fact that the boot isn't the most waterproof, means these take forever to dry out and can often be quite unpleasant on a rainy day. It also is softer than the older F22s, which had a more versatile, all-mountain flex where these tend to be stuck in the freestyle spectrum.
I'd personally stay away from these in the future simply because the lack of a removeable liner. The big draw of the F-series boots is the low volume, and while I don't have huge feet so it didn't matter that much to me, these have lost that advantage while keeping the compromise. I suppose if you have time to dry your boots between uses, or avoid the wet, these would be a fine buy, but I spend nearly every day in them and can't recommend them for that.
