Ecco Mens Biom Walk 1.2 - The complex structure of the foot evolved to allow efficient walking on soft ground, not pavement. In this modern world when youre moving on hard surfaces, Biom offers a natural, barefoot walking feeling without hurting your feet. Not only is it comfortable, its pleasurable. Its like walking on sand. Because Biom makes you use your feet and leg muscles differently, the body will need to undergo a transition phase to re-learn how to stabilize itself and move efficiently.
