adidas doesn’t want to encourage being backhanded. But their new adizero Feather II for guys and adizero Tempaia II for gals are designed to help you do just that. On the tennis court. Keeping with adidas’ emphasis on light, the Feather II weighs in at 11.8 ounces (size 9), the Tempaia II at 10 ounces (size 7). Each boasts dual-density SprintFrame construction, microfiber SprintSkin, and forefoot SprintWeb. And each are rolling out now to adidas.com.
