Hot Toys "Thigh Enhancers"?

[Supes78/Bats89]

OK, I feel kind of weird asking this question (and I expect there will be a few dirty comments made, lol), but I've seen on here where some collectors have done mods or customs using parts called "thigh enhancers" on some Hot Toys figures. Particularly, I saw a "Superman Returns" figure outfitted with a pair of them and I thought about doing the same thing to my SR figure. I was just wondering which HT bodies had these enhancers? I've seen them on more recent figures like Captain America and Hawkeye, but I'm hoping for some older bodies that can be picked up cheaply. Thanks in advance!

TTM21 the new truetypes that just came out have them

I have a few thigh enhancers. They seem unneccassary unless its for something like Superman
