I have a pair of 2013 Burton SLX boots in a size 10.5.
They are barely used, with no damage what so ever. Only a few scuff marks.
They don't have the liners though, if you have a size 10.5 liner it should fit.
If you have Burton boots that are size 10.5, the liner will fit perfectly.
If you check out Burton liners there isn't really that much of a difference between all of them.
It's the shell that's different on all the boots.
These are $630+tax on the Burton web site.

Turn your shitty old beat up boots back into top of the line booties.
I'm lookin' to get $150. Pics on request.
