Plantar fasciitis is the most common cause of heel pain in Australia, affecting millions of people each year. The sharp, stabbing pain felt in the heel — especially that first step out of bed in the morning — is caused by inflammation of the plantar fascia, the thick band of tissue connecting your heel bone to your toes.
The good news: the right orthotic insole can make a significant difference. Here's what podiatrists recommend.
Why orthotics help plantar fasciitis
Orthotics work by supporting the arch of the foot and reducing the stretch placed on the plantar fascia with every step. A well-designed insole distributes your body weight more evenly, offloads the inflamed tissue, and helps correct the biomechanical issues — usually overpronation or flat feet — that caused the problem in the first place.
Not all insoles are created equal. Generic cushioning insoles from the supermarket may provide temporary comfort but don't address the underlying cause. Clinician-grade orthotics, like those stocked by TBS Health, are designed with the specific biomechanics of plantar fasciitis in mind.
Top orthotics for plantar fasciitis
1. Formthotics Dual Density
Formthotics are our best-selling orthotic — and for good reason. Made from a heat-mouldable foam that can be customised to your foot shape at home or in a clinic, the Dual Density range provides firm arch support with a cushioned top layer for shock absorption. Ideal for plantar fasciitis sufferers who need both control and comfort.
2. Trekker Orthotics
Trekker orthotics are engineered for people who spend long hours on their feet — whether hiking, working, or simply walking through daily life. Their deep heel cup and firm arch support make them a strong choice for plantar fasciitis, helping to stabilise the rearfoot and reduce load through the inflamed fascia with every step.
3. PowerStep Protech Classic Plus
PowerStep is one of the most prescribed orthotic brands in the world. The Protech Classic Plus features a semi-rigid shell for motion control, a dual-layer cushioning system, and a deep heel cradle — making it an excellent choice for moderate to severe plantar fasciitis.
What to look for in an orthotic for plantar fasciitis
- Deep heel cup — Cradles and stabilises the heel, reducing impact and controlling pronation
- Firm arch support — Supports the plantar fascia and reduces strain during walking
- Full length — Provides support along the entire foot, not just the heel
- The right density for your body weight — Heavier individuals need firmer orthotics; lighter individuals can use medium density
Other treatments that help
Orthotics work best as part of a broader treatment plan. Podiatrists typically recommend combining orthotics with:
- Calf stretching — Tight calf muscles increase tension through the plantar fascia. Stretch morning and night.
- Heel padding — Gel heel cups provide additional cushioning for acute heel pain. Shop heel cups →
- Strapping tape — Low-Dye taping offloads the plantar fascia and can provide immediate pain relief. Shop strapping tape →
- Footwear — Avoid flat shoes and bare feet, especially first thing in the morning.
When to see a podiatrist
If your heel pain has persisted for more than 6 weeks, it's worth seeing a podiatrist for a full biomechanical assessment. They can prescribe custom orthotics if off-the-shelf options aren't providing enough relief.
