Zara booties black size 38 - 8 in womens

New with tags, no flaws. This is a Zara KIDS black with inside side zipper The shoe is marked at size 38 - measures approximately 10.25” from heel to toe on the outer soles. So, about a size 8 US in women’s. I bought this thinking it was 5.5 (as stated on the attached tag but it is wayyyy off - Don’t know what Zara is thinking!) It is narrow to medium width, imo from looking at it. Please see photos for measurement.
