The biggest mistake people make with plantar fasciitis is trying to push through the pain. Running, walking long distances, or resuming your normal workout routine while your heel still hurts will worsen the tiny tears in your plantar fascia and significantly delay healing. Recovery already takes a long time, with one long-term study of 174 patients finding that those who became symptom-free had dealt with pain for an average of two years before it resolved. Every misstep during that window can add weeks or months.
Here are the most common mistakes that keep people stuck in the cycle of pain and re-injury.
Exercising Through the Pain
Plantar fasciitis isn’t the kind of injury you can train through. Continuing to run or do high-impact exercise on an inflamed plantar fascia deepens micro-tears and creates a repeating loop of damage and partial healing. Jumping, sprinting, hill running, box jumps, and plyometrics all place enormous load on the band of tissue that runs along the bottom of your foot.
When your pain starts improving, the temptation to jump back into your routine is strong, but returning too quickly is one of the most common causes of re-injury. A smarter approach is to start with very short, low-intensity activity and build gradually. If you’re a runner, begin with short jogs, using landmarks like trees or telephone poles as stopping points so you can gauge how your foot responds before adding distance.
Swimming and cycling are generally safe alternatives that let you maintain fitness without loading the plantar fascia. Walking is fine in moderation, but if each step causes heel pain, you’re doing more harm than good.
Wearing the Wrong Shoes (or No Shoes)
Going barefoot on hard surfaces is one of the worst things you can do. Research using pressure-sensor gait analysis shows that people with plantar fasciitis walk with altered biomechanics when barefoot. Their stride shortens, and the heel can’t support weight the way a healthy foot does because the inflamed fascia where it attaches to the heel bone can’t function properly. Without cushioning and arch support, every step on tile, hardwood, or concrete sends unabsorbed force directly into the damaged tissue.
Flat shoes are almost as bad. Ballet flats, flip-flops, worn-out sneakers, and fashion shoes with no arch support let your foot collapse inward with each step, stretching the fascia repeatedly. If you’re dealing with plantar fasciitis, every pair of shoes you wear regularly should have a supportive insole and a slightly cushioned heel. Even around the house, a supportive sandal or sneaker beats going barefoot.
Relying on Anti-Inflammatory Medications Long-Term
Over-the-counter anti-inflammatory drugs can help in the first few weeks when your heel is acutely inflamed. But here’s what most people don’t realize: chronic plantar fasciitis is not primarily an inflammatory condition. Despite its name (the “-itis” suffix implies inflammation), the underlying process in long-lasting cases is degenerative. The tissue shows disorganized collagen fibers, thickened cells, and areas with poor blood supply rather than the classic signs of active inflammation.
That means taking anti-inflammatories for months on end may not address what’s actually happening in your foot, while exposing you to real side effects. Chronic use can cause stomach irritation, ulcers, gastrointestinal bleeding, and kidney problems. Short-term use for flare-ups is reasonable, but these pills aren’t a long-term treatment plan.
Getting Too Many Steroid Injections
Cortisone injections can provide dramatic short-term relief, and many people understandably want to repeat them. But repeated injections carry a real risk of rupturing the plantar fascia entirely. In one study tracking injection outcomes, 2.4% of patients experienced a plantar fascia rupture after an average of about 2.7 injections. That may sound small, but a ruptured fascia is a far worse problem than the one you started with.
There’s another reason to be cautious. Research on surgical outcomes found that patients who had received steroid injections before surgery had significantly worse results. The injections may weaken the tissue over time, making it less resilient whether you end up needing surgery or not.
Ignoring What Happens While You Sleep
When you sleep, your feet naturally point downward, which lets the plantar fascia tighten and shorten overnight. That’s why the first steps out of bed in the morning are often the most painful: you’re suddenly stretching tissue that has contracted for hours.
A night splint holds your ankle at a slight upward angle (about 5 degrees) while you sleep, keeping the fascia gently stretched. In one clinical trial, patients who used a night splint for eight weeks alongside standard treatment had significantly greater pain improvement than those who didn’t. Heel pain recurred in only about 14% of the splint group, compared to 29% of those without one. Night splints aren’t glamorous, and they take some getting used to, but they address a mechanical problem that stretching alone can’t fix.
Applying Heat Too Early
When your heel is throbbing, a warm soak can feel soothing, but heat increases blood flow and can amplify swelling in tissue that’s already irritated. During an acute flare, ice is the better choice. Rolling your foot over a frozen water bottle for 15 to 20 minutes gives you the dual benefit of cold therapy and a gentle massage along the fascia.
Heat has its place later in recovery, particularly before stretching, when warming the tissue can improve flexibility. But during the first 48 hours of a flare-up or after a day that left your heel aching, reach for ice first.
Ignoring Your Body Weight
This is the factor people least want to hear about, but the data is hard to ignore. A meta-analysis of 51 studies found that a BMI above 27 was associated with a 3.7 times greater likelihood of developing plantar fasciitis. The association was strongest in non-athletes, meaning it’s not just about how much you exercise but about how much load the fascia bears during everyday activity.
Every pound of body weight translates to roughly two to three pounds of force on your feet while walking. Even a modest reduction in weight meaningfully decreases the repetitive stress on the plantar fascia throughout the day. This won’t produce overnight results, but it’s one of the few changes that addresses the root mechanical cause rather than just managing symptoms.
Expecting a Quick Fix
Perhaps the most damaging mistake is assuming plantar fasciitis will resolve in a few weeks with the right treatment. The reality is more humbling. In the long-term follow-up study of 174 patients, only 54% were completely symptom-free at the time of reassessment, and those who did recover had experienced symptoms for an average of about two years. The range was enormous, from 41 days to over 10 years.
This doesn’t mean you’ll suffer for years. It means you should treat recovery as a long game rather than a sprint. Consistent daily stretching, proper footwear, gradual return to activity, and managing your weight are all more effective than any single treatment. In that same study, patients had collectively tried cortisone injections (93%), insoles (79%), rehabilitation exercises (66%), anti-inflammatory drugs (46%), and shockwave therapy (25%), among other approaches. No single intervention was a magic bullet.
Surgery is sometimes presented as the definitive solution, but partial plantar fascia release has a short-term success rate of only about 80%, and some researchers have questioned whether patients who underwent surgery simply improved due to the natural course of the disease over the same time period. A prolonged recovery period and mixed long-term outcomes make it a last resort after at least 6 to 12 months of consistent conservative care.
