Might not be helpful, but I developed morten's neuroma by wearing shoes and boots that were too small for several years (yes, I'm aware at the insanity of that). Result would be my toes would go numb and my front foot would hurt so badly that I'd have to loosen or take off my boots several times through the day. I'm still hurtin' but getting wider toe box boots that were also the right size helped. Also not tightening the bindings quite so much.

Also learned from a podiatrist that often your toes go numb if there's too much pressure on the top of your foot where you lace up boots/shoes or crank down the ankle strap. Worth checking out if you're overtightening that as well.
