The ones you put on your feet Qazzie.
Flats, loafers, or oxfords in the winter .... sandals in the summer. I only wear heels on rare occasions these days ... my poor old feet no longer tolerate them well.
Flats, or low-heel pumps for more formal occasions.
For formal occasions I go barefoot
Sometimes...insulated high top boots, rubber boots, dress shoes, 4 or 5 pairs of sneakers.
Ratty old chucks in the winter, ratty old birks in the summer
