Tall boots that climb up to the thighs show up a lot in pinups and sex scenes, framing the legs with shiny leather or latex while leaving plenty of bare skin above the tops. They usually get paired with lingerie, corsets, or superhero-style outfits, and they add a dominatrix vibe while a partner grabs the boots, spreads the legs, or fucks them hard. The contrast between covered calves and exposed thighs tends to get extra attention in poses that show off ass, crotch, and leg length.
