I'm still catching up and am about an hour behind, so sorry if the following opinion is outdated!
I don't see anything strange with LS walking around barefoot.
LS's shoes may have hurt her. Even if she hadn't forgotten her shoes at the bar, if her shoes hurt, she would've walked home barefoot. She likely felt comfortable in Bloomington, so she probably wouldn't minded walking barefoot. She probably also knew that she could just pick up her shoes tomorrow, so getting her shoes back wasn't a priority. *If* she got kicked out of the bar, as some speculated, she may not have had a chance to retrieve her shoes.
I remember countless friends who would walk home from a bar barefoot while I was in college. They usually didn't forget their shoes there, but either took off their shoes because they hurt or because it was nice out and they wanted to run through grass or whatever without ruining their shoes.
Point being, they didn't care that they were barefoot and weren't trying to find a more comfortable pair of shoes, unless they had plans to go to another bar (barefoot in bars somehow always seemed ickier than walking barefoot on the streets idk)
Also, if LS was blacked out or at least intoxicated, it's likely she didn't notice or care about her feet.
JMHO!
