According to TBlake the 1990 World Series inspired collab between Nike SB x Unheard of Brand x Anonymous Skateshop has received a cease & desist, requiring the Footwear giant to recall all pairs from inventory and retailers. No other information has been disclosed, but its safe to assume this cease and desist came from the MLB for referencing two of its major league baseball teams. The two pairs were scheduled to release this morning at 10am EST. but never hit Nike's online site.
There are currently pairs of each colorway available on eBay under retail. You may want to at fast if you wanted to purchase a pair as prices may drive up due to this recent news.
