La Sportiva Trango Extreme EVO (the silver and black color). Size 44.5 (11 USA). Like New In Box (LNIB) and purchased last winter. These are very warm and light weight, but I have a very difficult fit. Thought these would work, but wrong again. Unfortunately, the local store (Denver) where I purchased these boots doesn‘t have a good exchange policy. I wore these only 4 times on and tried every combination possible of socks, lace, and footbed; must continue my search. Asking $250 obo; these are $400 new. Absolutely LNIB !
