I am a big fan of both Vibram Fivefingers and Jika-Tabi, but I'm also a US Army soldier and guess what?  The US Army says I have to wear "shoes featuring only one compartment for all the toes" with the Army physical fitness uniform.  So I bought these.  They are the best running shoe I know of with one compartment for all the toes.  I run short distances (typically 3 kilometers) so I can't attest to their marathon performance, but for my needs they are perfect.  I'd recommend them to any soldier looking for a street legal VFF.

They fit really tightly, but that didn't cause me any problems running so maybe they are supposed to fit tight.  I'd probably buy a half size bigger next time, as they seem to run small.

It's also cool that they are named after Hattori Hanzo, a 15th century ninja who saved the life of Tokugawa Ieyasu.
