10 Crazy Inventions You Won't Believe Actually Got Made

3. Grass Flip Flops

There's nothing more annoying when you're taking a stroll down the park barefooted than treading in dog poo or cutting your soles on a hidden shard of glass - it completely ruins the pleasant sensation of freshly cut grass between your toes. Inevitably you end up putting on footwear to protect your feet, but with the specially made grass flip flops designed by Kusa Shoes you can experience the best of both worlds. These handy items of footwear afford you the safety and protection found with any regular flip flops while retaining that fresh grass underfoot sensation you know and love. Whether or not additional surfaces will be released in the future is unclear - experiments with sand flip flops failed as the sand kept falling off the flip flop, and concrete proved to be too uncomfortable in trial runs.
