The plantar fascia is an extraordinary structure that stretches along the full length of the foot and is very important in getting good propulsion in jumps and in walking. However, it is designed to cope with strain in an on and off kind of way, rather than be under constant load. Treating the sole of the foot will rarely fix the problem and often requires the structures around the plantar fascia to be treated to see change.
The three big things that need to be addressed to really fix the issue are:
- Muscular support of the arches of the foot
- Fascial mobility throughout the body and especially the lower leg
- Gentle support to reduce the load on the fascia while it heals.
1. Muscular support of the arches of the foot
As Leonardo da Vinci said, “The human foot is a masterpiece of engineering and a work of art.” When working properly, it allows us to run and jump and dance in the most extraordinary ways. However when it does not work in the way it was designed, then we can experience a lot of pain.
The foot is designed in such a way that it has 3 dynamic arches. By dynamic, I mean that they are designed to move and flex as we move, rather than be held in one place all the time. These are supported by complex slings of muscles and facia that work together to power us forward. However, if there is a weakness in the muscles that support the position of the foot, a constant strain is placed on the plantar fascia and it will start to get sore.
