This summer I bought some new ski boots (Nordica Double Six) and they are the same size as my old ones. I have Marker Squire bindings on Atomic Blogs. My old boots were 26.5 and these are 26.5, the shell length on the two is 3mm difference. The new boots are 305mm and the old were 302mm. Both boots snap in just fine but I don't know if there is more to it I need to worry about than just that. Also, if need be could I make a small adjustment in the heel peice binding to account for the 3mm?
