If you're a fleet-footed striker sprinting down the pitch towards the goal, every little bit of weight can make a difference. Nike's new GS soccer boot is the company's lightest ever thanks to its minimal design made of renewable materials.
A size 9 Nike GS boot weighs 5.6 ounces, which is heavier than a five-ounce iPhone and a full ounce less than Nike's next lightest boot, the 6.7-ounce CTR360 Maestri II FG. The company says it achieved the lightweight design with a material called "Pebax Renu" that's made of 97 percent castor beans. By using the material on the boot's sturdy bottom plate, Nike is able to reduce the weight of the plate by 15 percent. The Nike GS will be available in August for $300. [Nike]
