Overview
The plantar fascia is a strong band of connective tissue on the bottom of the foot. It starts near the heel bone, spreads toward the toes and helps support the arch as you stand, walk and push off.
How It Works
When the toes bend upward late in a step, the fascia tightens and helps stiffen the foot for push-off. This is part of the windlass mechanism—a normal way the foot changes from a flexible landing platform into a firmer lever.
Why It Can Hurt
Pain near the inner bottom of the heel is commonly called plantar fasciitis, although longer-lasting cases often show more overload-related tissue change than classic inflammation. First-step pain after rest is a common pattern, but heel pain can also come from the fat pad, nerve irritation, bone stress or the Achilles insertion.
What Usually Helps
Education about load, footwear advice, targeted stretching and gradual strengthening are common first-line tools. There is no single “release” point that explains every heel symptom. Sudden severe pain, numbness, inability to bear weight, fever, or a rapidly worsening foot needs assessment.
