Designed for players who don't just want an edge, but the whole blade, these Adizero Afterburner 9 TPU baseball cleats mean business on the base paths. A widened lacing system pairs with a molded tongue for a fit so snug and responsive it's like an extension of your foot. The new Sprintskin upper with lightweight mesh gets you to top speed and keeps you there with breathability and support. Underneath, a Lightstrike midsole powers your explosiveness and energy return. For players who know that every millisecond and every micrometer matter, these cleats give your speed and power a place to manifest. The only thing left is to leave the other team in your dust.
