Why did she take her shoe off, when I didn't ask her to, or tell her to?

I don't like asking people to do things, nor demanding them to, especially since it's wrong to demand... but, I was talking to her about her heels and about how the strap was missing on it. She told me she likes to cut the strap off of them, as a weird quark, instead of just buying strapless heels. She proceeded to take the shoe off and show me her feet and even told me that she has a high arch which was meant for heels of course, and even prefers to wear them.

But, again, I didn't ask her to take them off, nor did i say "take off your shoes", so, why did she just up and take them off?
