The Nasa ForceShoe takes wearable fitness trackers to a cosmic level. Resembling a pair of high-tech Birkenstock sandals, they are meant to be worn by astronauts in space in order to more accurately obtain useful information about their exercising habits and statistics. Honing in on load-bearing workouts in particular such as squats, deadlifts and bicep curls, the Nasa ForceShoe measures its effects on these astronauts.
According to Dvice, the data garnered from the Nasa ForceShoe is valuable as the possibility of traveling to other planets, namely Mars, becomes increasingly possible: "Astronauts on such exploration missions will need very specific training and strengthening programs to maintain bone and muscle mass, but they’ll also need strength to move on planets’ surfaces after spending a long time in microgravity." The data can also be applied to Earth.
