An exclusive Nike Air Zoom Spiridon is on the way, courtesy of U.K.-based retailer Size?, according to the shop's Instagram account and a teaser on its site

The lightweight runner debuted in 1997, and this drop will help celebrate the shoe's 20th anniversary. Based on the broken-up teaser photo and GIF, it appears that the shoe features traditional Spiridon materials, including its signature irridescent Swoosh. 

Nike has dropped a series of Spiridon releases over the past few years, including versions with updated materials and constructions, as well as collaborative editions like the recently relased Stash design

This Size?-exclusive Nike Air Zoom Spiridon has a scheduled sneaker release date of Saturday, Dec. 9, so it's likely that more detailed images of the sneaker will be available soon.

UPDATE: Official images have been released. The pairs will both retail at app. $148.
