UA Curry 4 was officially released in October 2017. Compared with the previous generation, the appearance has achieved a major breakthrough. It adopts a sock-shaped design, which is more in line with the trend. At the same time, the upgrade of the upper also brings more appropriate protection to the ankle. The shoe is made of fabric material and fine fiber synthetic material. The surface greatly reduces the weight of the shoe body, making it about 70 grams lighter than the previous generation, without losing the necessary protection; while the midsole without any technology seems lacking in sincerity, and the foot feel is slightly stiff, but the cushioning feedback is good, which is very suitable for speedy players to start at a high speed.
