These are Sorel's Glacy boots. 【Size】23.5cm 【Color】Black It's not just plain black; the material of the vertical pattern on the back is different, giving it a unique design. I searched high and low to get these. I used them for one season, along with other boots. I love them very much, but I've accumulated too many similar pairs, so I'm putting them up for sale. They will be shipped in their original box. Please refrain from price negotiations.
