The surge in wearable technology has certainly snowballed in recent years, from fitbits to smartglasses, but did sports brand Puma stake their own claim back in 1986?  Looking back at this retro advert, it certainly evokes fond memories of a simpler time; floppy disks, IBM computers and, well, the RS Computer Shoe! 

These trainers may not have been particularly light to wear, but the idea was there in principle.  Technological evolution moves at a blistering pace sometimes, but a good idea is a good idea - regardless of when it was conceived.
