Detail look at PUMA Fast-R NITRO Elite 3, the latest topracing shoes from pumarunning . Each shoe weighs only 170 grams, a reduction of 100 grams compared to Fast-R NITRO Elite 2, making it the lightest racing shoe in PUMA’s history. This significant weight reduction is achieved through the use of NITROFOAM ELITE supercritical nitrogen foam midsole. The midsole features a three-layer structure: carbon plates and other propulsion plates are embedded in either two or three layers of nitrogen foam, optimizing energy feedback efficiency. 📸 shuanghuoweiyan #kicksvision #puma #pumarunning #pumafastrnitroelite3 #fastrnitroelite3 #pumarunningshoes #racershoes #instakicks #basketballshoes
