As you may have seen, Tiger Woods continues to wear a customized TW 13 with a white toe while the retail version has a black toe. While there are other minor differences, this continues to be the biggest difference.
One way to make you TW13 like TW’s version is to paint your toe box white. Golfwrx.com member whcwhc did exactly that taping the toe box, and then spray painting multiple coats of white paint. While the paint appears to wear off after walking some rounds, the visible part seems to remain white.
