Now that we have the pros wearing wristbands with a different color for each wrist, I predict that within the next year we will see them wearing different colored shoes for each foot. Anyone wanna bet? Manufacturers would love it. Kids would need to buy two pairs of shoes to get the right effect. I'm going to seed the effort at the grass roots level this evening at my USTA team practice. White shirt, black shorts, one black wrist band, one white. . . even though I usually don't wear wrist bands. . . and then one black shoe and one white shoe opposite of the wrist bands to complete the ensemble. Complete write-up to follow.
