I imagine furries wearing shoes or not depends on what they do. With my furry characters, their feet are pretty rugged and are usually barefoot unless doing an activity which is safer with protection on their feet, such as construction, mining, experimenting in a chemical lab, stuff like that. Naturally, people like to make things less stressful on themselves if possible, so I feel it would make sense for furries to wear shoes if they feel it's more comfy and helpful.
