If the shoes on your feet or the pairs in your closet have their front tips curved upward, it's because they have toe springs.
The toe spring puts the foot in a perpetually flexed position. It's designed to make walking and running more comfortable and energetically efficient.
But Business Insider reports a new study shows toe springs may weaken the foot muscles over time, which could contribute to injuries like plantar fasciitis.
That could lead to plantar fasciitis. It's a condition characterized by painful inflammation in the plantar fascia tissue on the sole of the foot.
Common among runners, this injury affects 2 million Americans a year. It comes with a stabbing pain in the heels and arches, and is very difficult to repair.
