This designer did a fine job of making the image look as if it were in action. The shape of the shoe with the help of the shadow beneath it, help to indicate that the heel is risen off the ground, while the fades out laces indicate movement. Very good design technique for someone attempting to sell an athletic shoe.
The detail in this design is incredible. The designer did a very good job of identifying where the cut outs of the sandal will be. The highlights and shadows also help a lot to identify the details of the shoe design, and really do a great job of showing the traction you would be getting from the bottom of the shoes.
