I'd say they are one of the rarest sample huaraches. That pair and the other teal version and a huarache burst in the huarache racer are the only huarache samples I have come across that were never released. I have had my hands on some other huarache samples but they were just the samples of c/w's that got released. I couldn't see any difference either other than "sample" being written on the tag behind the tongue.
