I bought myself this cheap pair of geta from a shop I happened to walk by in Azabu Juban called Koizumi footwear.
The shopkeeper tried to tempt me with these (maybe because the ones I picked out are really for guys -- most of the geta and more formal zori designed for women are too narrow for my feet) but they were 3x the price, and I sort of pitched forward with every step. Their style is more authentic-traditional Japanese because of the two "teeth" on the bottom.
This pair, featuring a black velvety thong, cost even more, perhaps because each sandal was carved from a single piece of wood. Cloppetty-clop!
