I purchased these from an authorized retailer and had a Vibram sole professionally attached at a shoe repair shop for about 10,000 yen. However, when I tried them on, the size was too big, and I realized I couldn't wear them for everyday use, so I'm sadly putting them up for sale ( ; ; ) I think they would fit someone who usually wears a 27.5-28.0 size. (I'm a 27.0) Brand new, never worn, and equipped with a Vibram sole, so you can wear them right away! Thank you for your consideration!
