Vibram is the brand. The cobblers somehow glue it on to the sole of the shoe. Vibram comes in different colours to match soles of shoes. If you search vibram in the CL forum you will find lots of threads on it. Seems like vibram became popular with the CL lovers. As for the back heel I don't use anything and don't know if there is anything out there. HTH!I also use the protect your shoes transparent stick-on, but what is vibram? Is that the common term for all cobblers? Whatabout the back heel, what do you do to protect it? I just got my new Tribute in Hot Pink & I intend to get all my money's worth.![]()
