Authentic Lowtop women’s ace GG supreme bumble bee sneakers

I usually wear an 8.5, the shoe says it’s a 37.5 which is a 7.5 but I really think the sizing must be off because they have to be an 8 or 8.5 size. They are in very good condition only wore maybe 3 times . Just want to sell them. I actually think this style is discontinued, box and dust bag included
