Reebok silver sneakers EUR 39

Cute silver shoes from Reebok, good condition, worn for a few days on a cruise ship. Sparkly silver glitter and silver metallic upper with silver tinsel laces. Light scuffing on toe as pictured. Material unknown. No box. Please note the size label lists both Big Kids US 7 and Women’s EUR 39. I am listing this as US 8.5 because that is the EUR equivalent, and because that is my size and these fit me.
