Can someone help me out with this? I have a pair of Tecnica Diablo Inferno 60 boots (actually my son's from a couple years ago), and need to know what size they are to sell them online. On the bottom of the shell it says 260-265 and then 308mm. I don't know what the 260-265 means, and everything I've found online has indicated that the shell length should be in increments of 10mm (i.e. 305 or 315 but not 308). How do I accurately state what size these boots are?
