Formthotics orthotic insoles — heat-moldable, podiatrist-grade support for every activity
Formthotics are heat-moldable orthotic insoles used by podiatrists across Australia to correct foot biomechanics, redistribute pressure, and provide cushioned arch support without the cost or wait time of a fully custom orthotic. Designed in New Zealand and manufactured from Formax™ dual-density foam, each Formthotics insole moulds to the shape of your foot with body heat over time — delivering a personalised fit that improves with every wear.
This collection includes the full Formthotics range we stock: everyday and workfit insoles for work boots and safety shoes, running and sport insoles in single and dual-density options, cycling insoles, football boot insoles, plus Formthotics accessories including metatarsal dome pads, longitudinal arch pads, and heel raisers. All stocked and recommended by our podiatry team with fast delivery across Australia.
Which Formthotics insole is right for you?
Formthotics come in multiple densities, profiles, and activity-specific designs. Choosing the right one depends on your footwear, activity level, and what you're trying to manage.
Formthotics Everyday Workfit — the most popular choice for work boots, safety shoes, and trade footwear. A firmer dual-density construction absorbs impact on hard surfaces while supporting the arch through long shifts on your feet. If you're searching for workfit insoles or the best insoles for work boots in Australia, this is the one our podiatry team recommends most often.
Formthotics Dual Density (Red/Blue) — the classic podiatry-grade Formthotics insole, available in full-length and 3/4 length. A softer blue top layer for cushioning sits over a firmer red base for biomechanical control. Suits most enclosed everyday shoes and is commonly prescribed for plantar fasciitis, heel pain, flat feet, and general arch support.
Formthotics Dual Density (Red/Red) — firmer than the Red/Blue, offering more rigid biomechanical control for patients who need maximum correction. Available in standard and low-profile versions to fit tighter footwear.
Formthotics Sport Run Dual — a dual-density running insole that balances cushioning with support. Designed for road and trail runners who want more structure than a standard factory insole without the rigidity of a custom orthotic.
Formthotics Sport Run Single — a lightweight single-density running insole for runners who prefer minimal bulk and a closer-to-ground feel. Heat-moldable for a custom fit inside racing flats and lightweight trainers.
Formthotics ShockStop — maximum shock absorption for high-impact activities. The thickest cushioning option in the Formthotics range, ideal for occupations or sports involving jumping, landing, or extended time on concrete.
Formthotics Cycle — a thin, firm insole designed specifically for cycling shoes. Supports the arch during the pedal stroke without adding bulk inside a stiff cycling shoe.
Formthotics Football — designed for tight-fitting football boots where space is limited. A low-profile construction that still delivers arch support and shock absorption during high-intensity play.
Formthotics vs custom orthotics — how do they compare?
Custom orthotics are moulded from a scan or cast of your foot and offer the highest level of biomechanical control — but they typically cost $400–$600+ and take several weeks to manufacture. Formthotics sit in between a generic insole and a full custom device: they're heat-moldable and adapt to your foot shape over time, providing a semi-custom fit at a fraction of the cost. For many patients with mild to moderate plantar fasciitis, flat feet, or heel pain, Formthotics provide enough support that a custom orthotic isn't necessary.

Frequently asked questions
Are Formthotics good for plantar fasciitis?
Yes — Formthotics are one of the most commonly prescribed over-the-counter orthotic insoles for plantar fasciitis in Australia. The Dual Density (Red/Blue) and Workfit models both provide structured arch support and heel cushioning that helps reduce strain on the plantar fascia. For more information, see our guide to the best orthotics for plantar fasciitis.
How do I heat-mould Formthotics?
Formthotics mouldable foam adapts gradually to your foot shape through body heat during normal wear. For a faster custom fit, your podiatrist can heat-mould them in clinic using a heat gun or oven, shaping them directly to your foot in minutes. No special equipment is needed for home use — simply wear them and they'll conform over the first few days.
Which Formthotics are best for work boots?
The Formthotics Everyday Workfit insole is specifically designed for work boots and safety shoes. It's the firmest everyday option in the range, with dual-density construction that handles the impact of hard surfaces and long shifts. If you need maximum shock absorption (concrete, warehouse, construction), consider pairing Workfit insoles with the ShockStop model.
Can I trim Formthotics to fit my shoes?
Yes — all Formthotics insoles can be trimmed to size using sharp scissors. Each insole includes printed guidelines on the underside for common shoe sizes. Trim gradually and check the fit after each cut.
What's the difference between full-length and 3/4-length Formthotics?
Full-length Formthotics run the entire length of the shoe and replace the existing factory insole. They provide support from heel to toe and are the best choice for most people. 3/4-length Formthotics end before the toes, making them easier to fit in shoes where space is tight (dress shoes, some work boots) — they still provide full arch and heel support but rely on the shoe's existing forefoot cushioning.
