Plantar Fasciitis: An Issue of Overuse, Underuse or Age?

Plantar Fasciitis: An Issue of Overuse, Underuse or Age?

Plantar fasciitis! What is it, exactly?

  • How can a problem in such a small area of the body have such a big impact on the entire body?
  • How can exercise fix the issue if moving hurts?
  • What if plantar fasciitis isn't only an overuse issue, but also an issue of underuse?

Biomechanist Katy Bowman and biologist Dr Jeannette Loram get into what’s happening in the various tissues of the foot (including that it's not really an issue of inflammation as much as it's an issue of plantar fascia degeneration) and what to do about it. Jim Leuty of My Happy Feet joins in later, to talk about toe-spreading socks, foot mobility and making foot care part of everyday life.
