Adidas has unveiled the new ZG21 spiked golf shoe. The new shoe is said to weigh 20 percent less than any previous spiked model sold by the brand. This is made possible by a cushioning that is 40 percent lighter than the typical EVA foam in the market. The ZG21 will come in four models: men’s laced, men’s and women’s BOA, and a laced model for juniors. The BOA models feature the new BOA Fit System. The Adidas ZG21 will go on sale in Europe and the U.K. on Feb. 19.
