Sometimes, life is less complicated than you think. Say you’d like to buy a pair of running shoes, but there’s an overwhelming amount of shoes to choose from. Some shoes are promoted for different types of terrains, others for specific cushioning or stability or grip. This new study found the most reliable, scientifically valid way for each of us to pick the right running shoes, taking into account relationship between shoes and running injuries. What matters most, the researchers conclude in their review, is comfort. There you go. Just pick the shoes that you feel are the most comfortable.
