My ultra runner buddy suggested trying these zero drop shoes because they give me a more natural fit than my softer 6mm drop New Balance Beacon V2 (which is the most advanced running shoe on the market is). existed). done in my opinion.) Well, after a 2 mile run and another 1 mile in those medieval torture devices, I came to two conclusions: 1.) He's an idiot. And: 2.) No wonder he constantly complains about excruciating pain in his legs, knees, hips and lower back. Zero-drop shoes are junk for the hipsters of the running world, looking for tricks, looking for the next trend. If you want a "natural running experience", why wear shoes at all? It's cheaper and you'll still be in soreness after every run, combined with the inevitability of catastrophic injuries. Words cannot describe how much I hate these shoes. you have been warned
