Walking boots and slippers

That's the only footwear required. I really have a lot of different shoes, heels for presentations and conference, smart boots, high boots for concerts, shoes for music uniform, sandals smart and heeled, 4 pairs of trainers, for inside use and running, ski boots, ballet pumps... I could probably go on.
But how many pairs of shoes are in use? well just walking boots for my daily walk, and shop, plus Birkenstocks for every other activity. This is unbelievable!
