In reply to modaniel:
I've climbed in scarpa vapors, both lace up and Velcro, for years - numerous pairs. Never had to do any trickery. I find they break in really well after a few sessions. As 1 pound socks said, the trick in future is to buy new pair well before old pair are trashed so you can have weeks of overlap to break new ones in gradually.
As others have said, if its the length that's horribly tight (toe knuckles curled up) then you'll just have to accept no amount of wearing will change that. in which case sell them on here and start again.
BTW, I used to love the old orange Velcro ones and really don't like the new yellow velcros - totally different fit and far less precise. So now I use the yellow lace up with the black zigzag stripes. Love them! like the old velcros for performance but, obviously as they are lace up, you can get them even tighter and more precise. If youve not tried them I'd reallly recommend.
Good luck whatever you choose.
