Fantastic, stiff snowboard boot. I was searching for a boot for both an upgrade and better fit. I have a really narrow heel, and this is the first boot where my heel didn't slip. On my first ride out I noticed a quicker response changing edges, right from the boot to the board. I'm generally a 6.5 shoe, and got the size 6 (23cm). Fits perfect, though I do use custom foot beds.
Love the F22, and would totally recommend it.
