Apple’s about to get a big boost in the wearable computing department. 9to5Mac reports that Apple has hired top Nike Fuel Band and Flyknit shoe designer Ben Shaffer to work on the company’s upcoming wearable computing devices such as the long-rumored “iWatch.” This isn’t the first time that Apple has hired a design expert who worked on Nike’s fitness-tracking Fuel Band wrist accessory as earlier this year it hired fitness expert and one-time Fuel Band consultant Jay Blahnik to help work on its mobile accessories. Ties between Apple and Nike have traditionally been strong, especially since Apple CEO Tim Cook sits on Nike’s board of directors.
