Having released a tasty iteration of the CT300 not so long ago, as well as another version in collaboration with J.Crew, New Balance are really pushing the point home with a slew of new collaborative releases of the classic tennis sneaker. Originally released in 1979, the CT300 was one of the first ever tennis shoes produced by NB and was renowned for its superior cushioning and durability on the court. New Balance are clearly doing it big with this silhouette in 2014, hand crafting the most recent line-up at the brand’s Flimby, UK factory from premium materials. Furthering the Euro focus of the new release, Firmament in Berlin, Hanon in Aberdeen, 24 Kilates in Barcelona, and Sneakersnstuff from Stockholm and London are each producing their own takes on the sneaker.

Check out all four styles in the video above, which details the production journey.
