Science is catching up with the minimalist movement and revealing data that supports:
1. Many modern running shoes are like casts that force our feet to roll as we run.
2. However, our feet have evolved to splay out as they hit the ground. Our running form is optimal when we take shorter strides, land under our body and land on our forefoot.
3. If you choose shoes that have zero or low heel drop you increase your ability to land on your forefoot and stop 'rolling' (where you hit your heel first out in front of your body and then roll your entire foot). This allows for the shock of running to be distributed evenly up your whole body...rather than having it all hit right at your heel and vibrate your knees and hips.
