I think this is skyrim. Not sure what mod they're using but I tried playing it in vr and if you download the wabbajack modpack you can literally strip the npcs of their clothing using the grab mechanic, including their shoes. But their shoes come off together, so I didn't think there was a way for characters to lose one shoe in that gameio ... until now. Wish I could read japanese so I could figure out mods they are using.
