I don't even have a wallet - I have 3 forms of ID and a debit card, which I shove in the back pocket of whatever pants I'm wearing. And if I get cash, it goes in the other pocket. I carried a wallet all through high school but eventually got tired of the bulk, so I haven't had one for a decade or so.
Shoes... I have 6 pairs. 2 steel-toed boots from my Navy uniforms, one pair Doc Martens oxfords, one pair skate shoes, one pair good running shoes, one pair falling-apart-and-leaking running shoes. Oh, and I guess my $2 flipflops make 7.
