Product Information: THE NORTH FACE Down Boots NF51874 Nuptse Bootie WP VI Short US11 29.0 cm No box I purchased these for winter but didn't end up using them, so I'm selling them. I usually wear 30cm sneakers, and the size felt just right. My feet are higher-arched and a bit wider than average, I believe. Please feel free to contact me with any questions or price negotiations.
