Nike React Infinity 3 Black Road Running US 12

Wore 4 or 5 times. Plenty of wear left. Got the wrong size in the mail. My high schooler wore them anyway. Needed to buy a new size. Nike React Infinity 3 Style #: DH5392-005 Men's Black Road Running Shoes (Normally $150 new) Size US 12 The edges of where you put your foot in look like a different color but they are black and show no wear. It is something with the way the light bounces off that part of the shoe.
