The future will not realize these monstrosities...
Ugliness is their main crime. In fact, I'm almost certain that Adidas had no real plan or intention to manufacturing shackle sneakers (just look at them; they're a joke), and that all of this was just a big publicity stunt. We must see the shackle sneakers as existing in the same strange universe as this tennis match...
It's marketing in a state of desperation.
