Dragoon Lore Question

[Guiballad]

It's those shoes that have springs in the sole. Cannonically a dragoon is always wearing those.

But seriously, i figure that the soul crystal allows you something like limited manipulation of air-aspected aether to enable you to leap big distances and land with safety. This isn't based in anything around the dragoon questline just something that makes kinda sense to me based on the setting.

It's either magic, or the bodies of Hydaelyn's inhabitants are just much more durable than our weak Earth bodies. Various characters in in-game cutscenes are shown to be jumping from great heights, landing on their feet, and being perfectly fine. Off the top of my head, this happens with the WoL in the level 50 NIN quest, with the Miqo'te girl in one of the Amalj'aa storyline quests, and with the Scions when we confront Arbert and his gang for the first time.
