Hi All! I posted this in the shoes section but didn't get a response so I will try again here! I bought these pre-loved (the seller took a low offer) and I will get them authenticated but I am wondering if anyone has seen this before? The seller said they were a 6 so I believe the 230 number is chinese sizing but I don't know about the 1.5 and have never seen anything like that before. My other vara pumps were all from US sellers/stores so I don't know if this is common elsewhere. I'd love to hear any thoughts you may have!
