This model is known to run big, so I have them listed as a 8.5 because that is truly what they fit. I bought these for myself on poshmark, but they are a size too big for me. These are authentic, the leather is buttery soft and the shoes have lots of life left in them. Classic Gucci low-top sneakers. Smooth white leather upper. Signature green and red web stripe. Gold bee embroidery on the side. Lace-up front. Rubber sole.
