I mean the very specific sensation of knowing you're wearing exactly the right shoes for the task at hand. Like the way that the fabric moves is so perfect for the activity you know you made exactly the right choice. Some examples:
Ballet shoes for when you're dancing and pointing your toes
Slingback kitten heels for when you're seated to sip drinks in a nice bar
Comfortable walking shoes that support your ankles when you're hiking
A pair of light trainers in the summer that grip the pavement and don't make your feet sweat
Chunky boots in the winter that you can feel are completely waterproof
