Aww thanks, so glad I could inspire you!! <3The kind of spikes I used get screwed in so you wouldn’t be able to put them on the heel part of the shoe. They do, however, make low profile spikes like THESE you can iron on, it says they are “Great to add some studs and spikes to your shoes/high heels”. I’ve never tried them but they sound good to me.
I’m really rough on shoes so if I just used glue/iron on ones they would definitely come off which is why I personal like to use the ones that screw in, those suckers aren’t going anywhere!
Hope that helps a little
