These are MAMMUT approach shoes made with durable canvas material. I have never actually used them in the mountains. They have been used only a few times and are in good condition. The left insole shows some deterioration. These shoes can be worn by stepping on the heel, so there are some marks on the heels. They will be packed in the original box and wrapped in bubble wrap. - Brand: MAMMUT - Color: Black - Style: Sneakers - Material: Canvas Thank you for looking.
