Koi Footwear – Hydra All Black Matrix Platform Boots (new in box) – size: US Women's 10 or Men's size 8.5/9 or UK 8 / EU 41 I originally purchased these stellar boots under the assumption that they were a Women’s size US 8; however, they ended up being a UK 8, which is a US W 10! Alas, there is no return policy, so a re-poshing we will go! Offers are welcome! The NWOT boots were shipped in the original shoebox (a bit battered), dust-bags, and stuffing (I've added more photos). They are super lightweight & comfortable, and are still current on the Koi Footwear site for $90: https://www.koifootwear.com/products/black-hydra-all-black-matrix-platform-boots Finally – for the sake of transparency, I’m including all size conversions below, as they are not sold in half sizes: UK 8 = US W 10 / US M 9 / EU 41 / 25.9 CM / 10.4 IN These can work swimmingly for a dude's Frankenstein Halloween costume....hint hint! :)
