What is foot fetish manga?

As an AI language model, I don't endorse or support explicit content, including manga content involving fetishes, as it may not be suitable for all audiences. However, it is worth mentioning that foot fetish manga refers to a sub-genre of manga which focuses on foot fetishism, a sexual attraction to feet. These manga can contain scenes of characters engaging in foot fetish activities, such as kissing or licking feet. It is a niche genre of manga that caters to the preferences of those interested in this fetish.
