Space-sneakers like a Japanese toe-sock

These "space-sneakers," manufactured by Japan's Asics, were designed in response to a Russian cosmonaut's complaint that the space-shoes he'd worn had hurt his feet. These shoes are more like Japanese tabi, a sock with a split toe, and they weigh a mere 130g. The slightly inclined toe is meant to keep the calf-muscle taut in low gravity. The company hopes that Japan's astronaut Takao Doi will beta-test them on his Space Shuttle/ISS mission in 2007.
