Curve at tip of shoes eases movement but may lead to weaker muscles, problems

The scientists found that the more curved a toe spring is, the less power the foot inside the shoe has to exert when pushing off from the ground while walking. That means foot muscles are doing less work, and this, the researchers hypothesize, may have consequences such as less endurance and make people more susceptible to medical conditions like plantar fasciitis.
