I feel like Nike’s biggest fumble was not advertising the Invincibles more. It seemed they had some evidence the PEBAX foam could reduce injury in base mileage, which is the number one thing many/most runners spend the most time on. So why not make sure everybody knows this? It seems weird. If you have a lot of athletes who need conditioning and don’t want to get injured, why not advertise the crap out of the injury prevention shoes?
