I bought these at an REI sale, but they don't fit me. They were used in a photo shoot and are tagged accordingly, but haven't been used beyond that. I am asking $225 (includes shipping). The boots seem to be appropriate for heavier duty stuff (certainly appropriate for anything up to 7000m I would imagine). Here is a brief description. Please let me know if you have any questions!
