These are Mammut mountaineering boots. They have a heel welt, so I think they're suitable for summer mountains. - Size: UK 8 / EUR 42 / USA 9 They should fit snugly for someone who wears 25.5 or 26 cm shoes with regular socks. Part of the sole on the right foot is missing. See photos 3 and 4. It doesn't affect use. They are a bit cleaner in person than in the photos.
