THE NORTH FACE Nuptse 28cm NF51585 Nuptse Bootie 　　The North Face Snow Boots Model Number: NF51585 【Quality】 Upper: Synthetic Leather 　　　 Synthetic Fiber Sole: Rubber Overall, they are in good condition, but please note the following: There is a white stain on the inside of the left shoe (see photo 3). I tried wiping it with water, but it reappears, so please be aware of this. Also, I usually wear sneaker sizes around 27.5-28cm, but after wearing them once, they felt a bit small and were difficult to put on. I think they would fit better for someone who usually wears sneakers around 27cm.
