Also, apart from the general comfort (which is fantastic), one immediately noticeable benefit is that previously I found I was (unconsciously) curling my toes back slightly to compensate for lack of support. Now that the foot is held in place properly front to back, with the foot comfortably locked, the foot just relaxes and lets the ankle flex naturally with the boot. Much smoother less awkward, removed a lot of strain from my ankles too. And no pressure on the toes from the foot wanting to slide forward. It literally changed my riding for the better, not just my comfort.
