I have 9.
1 pair each of sneakers, hiking boots, barefoot shoes, bicycling shoes, trail running shoes, rock climbing shoes, flip flops, loafers, and steel toe work boots.
Unless I am travelling, I usually wear (wash & repeat) 4 shirts, two shorts and one pair of jeans. For travelling, I have extra clothes as its not always possible to do laundry when you are hopping cities every one or two days.
