I've always heard that sometimes the art director and photographers have models wash their soles before a shoot and sometimes the make-up people have to scrub the bottoms of the model's feet. I remember hearing some model complain that she had to have 2 or 3 people hold her legs while another had to use a small brush on her feet. She said it was torture and she laughed her head off. It must be kinda normal for this because it seems to me they talked about this on a Sports Illustrated video somewhere.
I used to work at a hotel and I also remember a local Miss teen USA pageant being held there and of course they're running around barefoot during the swimsuit rehearsal (which of course caught my attention) But after the rehearsal all the stage moms would clamor around their daughters primping and fawning until everyone went out for an event (off property) all but a few left but the ones who stayed went back to their rooms exept 2 really cute contestants that I found laughing their heads off in the ballroom. At first I just thought they were fooling around like teenage girls usually do but when I walked in 2 of the mothers where holding a wildly squirming teen as she lay across 3 or 4 chairs and the other contestant was sitting with a bucket of water and a big scrubbing brush at her feet scrubbing away like crazy. Obviously tickling the hell out of the poor teen contestant. They all were laughing, even the mothers but they were still holding the girl down with all their might.
I stood there, even when they looked over at me but I couldn't leave. I was mesmerized by this fantasy come true. Actually If it were my fantasy I'd be the one tickling!! Anyway they finally let the girl up and she wiped her eyes and checked the bottoms of her feet. Now I realized she was probably seeing if they got clean. But back then I couldn't figure out what they where doing. Then she said "Ok your turn" pointing at the other teen. Everything kinda got quiet for a second and they all looked over at me like "Can I help you?" This was a really awkward moment so I smiled and walked away. I got about 20 paces away and said "fuck it when am I gonna witness something like this again so I turned around and walked back to hear almost screaming coming from the other girl. They weren't really holding her down as much and she was sitting upright shaking her arms in the air violently trying to endure the tickling/scrubbing but it only lasted a few minutes untill she got up and said "no more, no more" or something like that. They got their things and left still kinda laughing and joking around. Like I said I couldn't figure out why they were washing each others feet back then . I just figured it was some hazing or ritual pagent crap until I heard about the model's foot cleaning thing years later
PS Before anyone gets bent out of shape... almost all of the "Teen USA" contestants are 18 and don't look a day under 23 believe me
