I can just see it now: the multi-shaded stripey feet and ankles of students on the first day back at school- damn those gladiator sandals.
If they had the unfortunate circumstance of having to work in a lab all summer, those months of crocs would've left the feet a nice pale snow shade, about 4 shades lighter than the rest of the leg. Hot.
The flip flop tan is a standard "V" on the foot, and looks quite elegant at times, lengthening the foot to it's most attractive.
Let's go barefoot for a while now...
