I have 3 pairs of footwear near my front door atm:
1) The one I use most nowadays is a pair of unisex black and white ASICS running shoes. I got my foot dimensions scanned in the store so these ones are perfectly fitted for my feet.
2) A pair of cheap cloth black flats. The right shoe has a small hole in the front but I haven’t had time to find a new pair. I put black tape over it for a time which came off. I have very long, narrow feet, so it’s hard to find shoes that are cheap, fit me, and look good, especially in most places outside of North America.
3) A pair of black high heels, medium-thick heel thickness and medium height. They are a standard uniform size for office work in my country.
When I was a teenager I worked at a sports clothes and footwear store over one summer. I remember I learned to quickly “VI” people that way, through noting their appearances and then checking through talking with them about their lifestyle and hobbies.
