The Nike Bomba Pro II is completely redesigned from the first version, making it lighter and more flexible than ever before. A new synthetic upper material provides the fit and ball feel of leather while remaining light and not overstretching. Inside is a die-cut EVA sockliner that disperses pressure from the outsole and cushions the arch and heel. The Bomba II got a brand new rubber and TPU outsole as well, with conical studs to enable rotation underneath the ball of the foot. The rest of the foot uses bladed studs that really dig in for added traction. Wt. 9.8 oz.
