I mostly wear Converse low-tops, but I do occasionally slip into some slip-ons or flippy floppies. Anything that allows me to not wear socks.
My favorite to wear right now are a pair of Chucks that I found at the Ross Dress For Less in my town. They're a really dark blue, with three other shades of blue rubber and like nine shoelace holes on each side. Quite comfy and different from the standard Chuck Taylor.
