A unique feature of this shoe is the composition of the upper material. The fine textile knit with lateral stitches in crepe structure and the patches with the brand's logo in 3 languages clearly set the overall tone of the design. The TPU elements in the lateral heel area, the heel loop and the narrow, squarely perforated lacing strips also set their structural accents. Often Smaller Sizes The sole is made of unmistakable, styrofoam-like boost material that provides light, strong cushioning. The outsole is made of rubber with a punched honeycomb profile, which keeps the weight of the show rather light, but reduces durability. Customers on adidas.de unanimously describe their first-hand impressions with the shoe as extremely comfortable. The only caveat is that the available sizes are a little too small in general.
