These bright Nike running shoes derive their concept and performance from the Chinese finger trap. This can be seen in the cross-hatched design the shoes possess.
The shoes mimic the classic toy in that they tighten when intense movements are made, but are soft and flexible while they are not in use. Similarly, the Chinese finger trap only gets tighter when there is movement or resistance. The difference is these shoes aren't meant to trap one's feet -- although that would surely encourage longer jogs.
The cross-hatched patterns also serves to create a visually stunning and intriguing style that is only accentuated by the mixing of the striking blue and yellow colors.
