Does stretching help plantar fasciitis heel pain?

Short answer

Yes. Stretching lowered pain by about 1 point out of 10 more in the first weeks, and stretching the sole directly beat stretching the calf. But after 6 months to 2 years, most people got better whatever they did, and there was no difference.

Does stretching help plantar fasciitis heel pain?
'Stretch the tight spot → less pain' — does this formula hold?
Plantar fasciitis is pain in the thick band under the heel, and the first steps in the morning hurt most. Stretching the sole and calf is the usual advice. We checked whether pain actually dropped, and how long the difference lasted.
Stretching cut pain in the first weeks
14 points lower out of 10
A 2023 analysis that pooled 236 studies (15,401 people) found stretching lowered short-term pain by 1.14 points out of 10 more than doing nothing. A 2026 analysis of 12 trials that pitted stretching against other treatments found no difference in pain between them.
Where you stretch mattered
Stretching the sole beat stretching the calf
A trial of 101 people with heel pain for over 10 months compared two stretches for 8 weeks (82 finished). Stretching the sole directly without bearing weight cut worst pain and first-step morning pain more than standing Achilles tendon stretches. An analysis of 8 trials also put sole stretching ahead.
But after 2 years, the gap was gone
94% of 66 people had less pain
After 8 weeks, everyone switched to sole stretching. Checking 66 people 2 years later, there was no difference in pain between the two original groups. 94% had less pain, and 77% had no limits on leisure activities.
Strength training worked faster
Ahead at 3 months, no difference at 1 year
In a trial of 48 people, those doing single-leg heel raises with a towel under the toes every other day scored 29 points better on foot function at 3 months than those doing daily sole stretches. At 6 and 12 months, there was no difference.
Time was the biggest factor
Adding exercise made no difference in pain at 6 months
200 people all got advice and custom insoles. Adding 12 weeks of strength exercise changed 6-month pain by just 0.11 points out of 10, which was no difference. All groups among these 200 improved gradually, with the biggest gains in the first 3 months.
Bottom line: stretching eases early pain
If you pick one, stretch the sole; in the long run, time does the work
Stretching lowered pain by about 1 point out of 10 more in the first weeks, and stretching the sole directly beat stretching the calf. After 6 months to 2 years, most people improved whatever exercise they did, with no difference. Think of stretching as a tool that eases early pain.
