There's been a couple of takes on shock-absorbing feet-tech in the Portal-verse. Now, someone's trying to make impact absorbing footwear for real.
Meet the Enko running shoe (via Engadget): a trainer with two built-in pistons that's the result of 12 years of work by engineer Christian Freschi. Those pistons not only absorb the impact of running (and, in this case, very small falls) but also stores the energy and returns it when you lift your foot.
