NIKE VAPOR PRO 3 HERITAGE HARD COURT TENNIS SHOES | Tennis 。The Vapor Pro 3 provides bounce and burst from side-to-side movements to scrambles to the net, so you can stay in the point. With springy Air Zoom cushioning and Nike Claybreaker technology that makes the shoe lighter than previous Vapors, it’s primed to last to match point on the red dirt Clay-Ready Nike Claybreaker technology helps give you enhanced traction and less buildup on clay courts. Added grip in the forefoot and midfoot work with a wide traction pattern to help you slide with control. We used traction maps, pressure maps and analyzed clay buildup areas for the design. Then we tested it on red-clay courts in Europe in multiple clay-weather conditions (cold, warm, wet and dry) Forefoot Flexibility The forefoot is more flexible because we shrank the Air Zoom unit and placed it where your foot feels the most impact. You still get responsive cushioning at the highest push-off point of your forefoot, but now there’s more flex Stick and Cut The outsole is made of a new rubber compound that’s lighter than Vapors of the past. It allows you to decelerate, plant and back into position without feeling like you’re rounding off your cuts Improved Feel We kept the same midsole foam and outsole pattern you loved on the Vapor 2 and improved the secure feel around the midfoot and heel for shaper cuts Deeper Flex The supportive forefoot piece has a deeper flex notch to improve flexibility Enhanced Fit A full midfoot fit band helps you pull the laces tighter to enhance No box
