Thinking about shoes and collections

My first year of college was in SoCal. I am from the Midwest. I stayed with my relatives that year. My cousin, who was a senior, had an interesting, to me, shoe collection. It included one pair of Sperry canvas CVO, Sperry two eyelet leather boat shoe and a leather pebble grain shoe in tan. I am not sure if he had a Chuck Taylor basketball shoe in black but he could have. How simple things were back then for him; practical and useful for his climate. Now, as an elder back in the Midwest, I have a shoe collection. I am not sure why I do. Perhaps because I like them and I used to go places and wear them. Humans seem to collect what they like; cameras and lenses, books, linen shirts, blazers, etc. Any thoughts on "overdoing" it by collecting things?
