The tracks on the bottom don't show up that well in most soil, but they look way cool.  The color and quality of the prints are excellent, and we haven't had any quality issues with the material or the fit.

My boys think these are the bomb.

However, please don't wash these in the washing machine.  I did, and all the flashers except the eye in the back stopped working.  Also, the colors fade a bit.  I may very well buy more of these once the old ones get particularly worn.
