I purchased these new on Rakuten in 2024, so I am the original owner. The size is 27cm. They were a little tight on me, so I'm selling them. Please judge the condition from the photos, but there is some wear on the soles and part of the plastic on the laces is damaged and has been repaired. I wore these more on snowy days than for mountain climbing. I think the soles are very non-slip. The insoles still seem to be in good condition. I personally don't notice any concerning odors, so I don't think it will be a problem, but please refrain from purchasing if you are sensitive to such things.
