A BVG special edition sneaker has been created in cooperation with a little known sports brand ... Adidas. So, what makes it so special - its tongue contains an annual ticket for Berlin's public transport system, meaning the lucky owner of these trainers won’t be stuck searching for their ticket in the rush hour commute, and can glide gracefully through the turnstile.

They haven’t stop there, the pattern on the heel of the trainers takes inspiration from the underground's interior décor - now we never thought that would come into fashion, did we?

All this makes the model limited to only 500 pieces, a sought-after collector's item, which is already sold out. A marketing initiative that has brought a lot of attention to the BVG.
