Does Wave wear shoes or boots?

I have seen plenty of submissions that state Wave's footwear are shoes by having them not as long as boots in those submissions. But 1 has not only stated they're boots by giving us a peek that they're boots longer than shoes under her pants, but the title even saying they're boots.

So is the footwear Wave the Swallow wears shoes like that of Storm, or boots like that of Jet? What are under those purple fire over white background pants? And if you have an answer, Do you have proof that your answer is correct?

And sorry if this bothers you. I just felt like I needed to ask because I enjoyed PeaceBeast92's work.
