Scarpa mountaineering boots. They fit me well enough to wear, but if I walk a long distance in them they give me heel blisters, and I finally replaced them.

These are a well-insulated single leather climbing boot that accept step-in crampons. They are good as heavy duty hiking boots but are designed for ice climbing and mountaineering. They cost well over $300 new, price is obo.

They are mens size 11.5 or 12, or about euro 46.

Please note that they are somewhat dirtier than in the photo, as I have used them since the photo was taken. They are in good, but not excellent, condition.
