Women emit pheromones from a few areas in very concentrated doses. One is their feet and the other is their crotch. Some men like the smell from both areas, some men like the smell from either, and some men like the smell from one or the other. However, for men who like the smell from one or the other pheromones are an incredible turnon.
The other reason is often because it was taboo during childhood or because it developed early as a fetish.
Note that for a given man one or all three of these may be at play. :) Anyway, if the kink is not harmful to the relationship (one-night stand or long term), just enjoy it.
