Yoo Give your opinion about porn induced fetishes

Well porn about feet or high heels IS a novel source of arousal. Sometimes the shock or surprise of a certain material can trick your mind into thinking it's very arousing, especially if you begin masturbating to it. If you haven't looked through the site Your Brain on Porn (YBOP), they have some good articles, which I've linked below, that go through why porn addicts have shifting sexual tastes.

Is my fetish porn-induced?
I’m straight, but attracted to transsexual or gay porn (or gay attracted to straight porn). What’s up?

Especially after a long streak, your mind is dying for sexual stimulation, and will willingly accept whatever you give it as very arousing and pleasurable stuff. If you have sex with a real woman, then your mind will find her more arousing every time. If you just PMO again, you're almost in a deeper hole than from where you began.

Your high heels fetish really is from the biological mechanisms that are constantly looking for novelty. I am very pro-sex and pro-happiness, and I don't think having a foot/high heel fetish is a bad thing. I personally know people who like feet stuff during sex, and they have on-and-off hookups every once in a while, have their life under control, and are not afflicted with porn addiction. However, it is clear to see that your fetish was porn-induced, and will likely bring you confusion, shame, and guilt down the line. This will likely escalate into other "worse" fetishes as well. I would go for a hard mode 90 day reboot, and then rewire with a partner. Once you're having consistent sex with 100% erections, then you can try some of the foot stuff WITH A PARTNER, NOT WITH PORN. If you still like it, then hey, cool, you just like feet a little. Odds are though, your porn mind is just telling you that you do, and once you start having good sex, feet will seem weird.

Coming for someone who was really into trans and feminization stuff, it's really hard to tell what you really like and what porn is making you like. After the 90 day reboot and a couple months of just really vanilla sex, I could easily discern some things I'm interested in (role-play, etc.), and things porn was just making me like (non-con, being penetrated, humiliation, etc.). I went in with the attitude to see what I really liked, and came out knowing what I really like. You shouldn't be afraid of having a foot-fetish (it's not that bad aha), but if it's really not you, you shouldn't be indulging in it. And most importantly, no matter what fetish you're trying out, you should always be carrying it ouy WITH A PARTNER, AND NOT PORN.
