These dark gray (almost black) slip-on shoes are made of synthetic fiber and are caregiver shoes with Velcro closures. At first glance, they don't look like caregiver shoes due to their color and design. These are "Tanpopo Biyori" caregiver shoes, known for their lightness and ease of wear. They have only been tried on and are in like-new condition, but since they have been stored at home, the "product condition" is listed as "no noticeable scratches." Thank you for looking.
