Thank you for viewing this item. I purchased these shoes on this site the other day, but I'm selling them because they felt a bit tight on my feet. I've generally been able to wear mountaineering boots from brands like La Sportiva and Lowa in EU sizes 41-42 without any problems, but these ASOLO mountaineering boots have a narrower fit. People with high insteps and wide feet, which are common among Japanese people, may find them tight. Please use this as a reference for the fit. The age of the shoes is unknown, but there is almost no wear and tear on the sole grooves, scuffs, or the shoes themselves. If the fit is right, I think they will perform well on the mountain.
