Grass shoes

Walking on a nice, slightly soft but not muddy, lush bit of grass is usually more pleasant than walking on asphalt. Even more so if you're walking barefoot. But in the city there is more asphalt than grass, and going barefoot is not always healthy or legal.

The solution is to strap two boxes of grass to your (bare) feet, providing both comfort and protection. You can wiggle your toes happily as you go about your daily ritual. At work, you kick off your shoes under your desk (don't you?) where they are illuminated by grow-lights if there is insufficient natural light. At home, you place them in a specialized grass-shoe-tending device which waters them, mows them, aerates the soil as necessary, etc.

Grass shoes are not completely utilitarian however! Flowers or very small shrubs planted around the outside can express your personality or (if you have multiple pairs) your mood that day. Bonsai aficionados can practice their meditative art at any time, such as during dull meetings or while stuck in traffic. And your feet, since they are not confined in shoes but spend the day among the clover and lavender, will never smell bad.
