Zig Zagged: Preparing to fight, Alice decides to switch to more sensible shoes. These "sensible" shoes are still high heeled, but they do not contain the "ridiculous additions" as her previous ones. However, it turns out these are genuinely practical, due to the odd physics of the area. Then it turns out that was just a bluff, she's Cherry Tapping. Except that was a bluff, her friend just turned off the gravity, so now shoes don't matter and the points of her heels (sharpened or not) are effective weapons...
Averted: Alice's battle outfit contains sensible, flat-soled boots to begin with.
Enforced: The writer and/or artist has a fetish for women in high heels, and lets that override practicality in designing Alice's footwear.
Lampshaded: "I did all of that while wearing heels!"
Invoked: "There is no way I'm going to be seen without my heels, even in a fight".
Exploited: Finding herself wearing heels in a fight, Alice uses her heels to stomp on her enemy's feet and jab them in the chest.
Defied: Alice is designing her battle outfit. While the heels are sexier and look good with the outfit, she decides to go with a more sensible pair of army boots.
Discussed: "Who'd thought fighting in heels would be so effective!"
Conversed: "How can you possibly fight in those heels?"
Deconstructed: Due to constantly fighting in heels, Alice is viewed as a clumsy and slow fighter, bordering on being ineffectual, and has broken her ankles a few times.
Reconstructed: But constant Training from Hell in them has made her ankles stronger and has improved her balance.
Plotted A Good Waste: The fact that Alice wears high heels for every occasion, including fighting and mountain climbing clues in readers that something's not right. It is later revealed that Alice's legs have shortened tendons, thus making it necessary for her to wear heels or she would otherwise walk on her tip toes.
