Release dates of sneakers getting moved around is not uncommon. A variety of factors can contribute to a release getting moved up or back. With the COVID-19 pandemic release dates have been more dynamic than ever, as it seems that more release dates have been postponed than have stuck to their original date.
The latest example of release moving to a point further in the future is the “Varsity Royal” Air Jordan 3. Although the sneaker had already made its retail debut overseas, it now appears that this colorway will not make it to domestic store shelves until sometime in October. If you want to, you can try to score a pair on eBay right now.
