The flagship from adidas has evolved once again and now presents the Ultraboost 22 for women. Energy-returning cushioning and a flexible outsole ensure optimum comfort. Woven mesh upper material in the various areas of the foot and the bootie construction ensure a comfortable, sock-like fit. The running shoe has a Responsive Boost midsole and a stabilising torsion system to give the foot extra support. The Linear Energy Push System provides more responsiveness than ever before. The adidas Primeknit was developed to provide a natural foot movement, a comfortable fit and less skin irritation - more stability in the midfoot area is the order of the day. Thanks to the narrow cut heel area, friction and blisters are avoided. The whole thing is rounded off with an anti-slip, flexible rubber outsole.
