hey guys, I rode the 2014's. I also owned the 2013's for about a month.
Leo, the new straps are only for the ankles. I don't remember exactly but I was under the impression that they still have regular genesis toe straps.
Are you making sure your heels are all the way back when you do them up? maybe hammer your toes a couple of times with your hand to get them all the way in.
EDIT: the toe straps are new too
As for the 2014's, yes, the new ankle strap is comfy...but so is the one on the 2013's.
the new straps are not in response to a problem with slipping ladders, it's just Burton pushing binding design.
