The 2012 strap is the same as 2011 (i think) and can be worn either way, personally i find it very comfortable worn toe. The Kaiju have a reasonably soft toebox too but the strap doesnt need to be cranked as much to get good response like that so I'd suggest giving it a run or two. Doesn't look as good mind.
But assuming you cant get replacements and you don't want to go toe, you might find that tweaking the binding size adjustment makes a big difference to get the strap more vertical (while still cap).
Hope you get it sorted one way or another.
