Webcomic Feet Finder: Everblue

Everblue the webcomic takes place in a world of seemingly endless ocean, where human civilization is limited to numerous floating cities that are themselves confined to a long belt of ocean that stretches from the north to south polls. Beyond this belt is the titular Everblue, an unexplored expanse from which no explorer has ever returned.

However, when a young shipwright meets a happy go lucky drifter after his boat crashes into the docks (through no fault of his (mostly)), events are set into motion that will force the shipwright from her home and the two of them on an adventure to explore the Everblue. However much can happen in an endless ocean and it is unknown if that which awaits them is scarier than that which already pursues them. (first comic)

Luna

Before she met Ten, aka happy go lucky drifter, Luna was just an ordinary shipwright. Okay that's not entirely true as she's also has a hobby of exploring the long untouched submerged sections of the city contrary to religious taboo and she's constructed a boat built around lost technology. But other than that, not so inordinate.

One of the things that makes this series so great for foot lovers is that Luna is perpetually either wearing sandals or just plain going barefoot. And it's not uncommon for the artist to show her going from a state of the former to the latter.
