Snowa Boots

I bought snowboard boots from Andele, but the size on the box doesn't match reality - the box says 45.5, and I am size 44, but they were slightly tight, so realistically, they would fit size 43 or 43.5. I haven't worn them myself, but the previous owner reportedly wore them 10 times on the mountain! The boots are really in excellent condition. New boots like these cost around 200 euros.
