From the Ground Up.
— CORE p.f
Designed specifically to relieve heel pain caused by plantar fasciitis. Clinically targeted cushioning and arch support that distributes pressure evenly — so every step hurts less, starting from day one.
What is plantar fasciitis — and why does your heel hurt?
Plantar fasciitis is one of the most common causes of heel pain. It happens when the plantar fascia — the thick band of tissue running along the bottom of your foot — becomes inflamed and overstressed. The result is a stabbing, burning pain in the heel that's typically worst with the first steps in the morning or after long periods of sitting.
It affects runners, people who stand for long hours, and those who simply have feet that aren't getting the support they need. Left unaddressed, it tends to get worse. The right insole doesn't cure plantar fasciitis, but it can dramatically reduce the load on the fascia — giving it the chance to heal while keeping you moving comfortably.
- Sharp heel pain with your first steps in the morning
- Pain that worsens after long periods of standing or walking
- Aching or burning along the arch of the foot
- Tenderness at the base of the heel when pressed
Targeted relief, layer by layer
An orange ACF technology cushion pad sits directly under the heel — the exact epicentre of plantar fasciitis pain. This high-density pad absorbs over 97% of heel strike impact, dramatically reducing the stress that travels through the fascia with every step.
Plantar fasciitis is often worsened by an unsupported arch that overstresses the fascia. A contoured support shell follows the natural curve of the arch, distributing bodyweight evenly across the whole foot instead of concentrating it at the heel.
The insole is engineered to spread load across the metatarsal area, heel, and arch — the three zones that carry the most pressure during walking and standing. Less concentrated pressure means less strain on the already-inflamed fascia.
Excessive foot rolling (overpronation) is a major contributor to plantar fasciitis. A reinforced lateral support structure keeps your foot tracking naturally — reducing the side-to-side motion that repeatedly strains the plantar fascia.
A breathable sports mesh top layer keeps feet dry during the long hours of standing or walking that plantar fasciitis sufferers often can't avoid. Anti-fungal and anti-bacterial treated for lasting hygiene in any shoe.
Recovery from plantar fasciitis takes time — weeks or months of consistent support. Wear-resistant materials throughout mean CORE p.f maintains its therapeutic effectiveness through the full recovery period, not just the first few weeks.
Three zones.
One pain-free step.

①Heel Pod — The ACF Cushion Difference
The orange ACF technology pad positioned directly under the calcaneus bone absorbs over 97% of heel strike impact — more than standard foam or gel alternatives. This is the defining feature of the CORE p.f design and the primary driver of pain relief.
-
②Arch — Fascia Load Reduction
A contoured polymer arch support lifts and holds the arch in its natural position, reducing the tensile load on the plantar fascia. Less pull on the fascia with every step means less inflammation and faster recovery.

③Lateral Edge — Pronation Control
A reinforced outer edge prevents the inward rolling that overtaxes the fascia, particularly important for flat-footed individuals and those who stand for long periods on hard surfaces.

Before you first pain-free step
Will these cure my plantar fasciitis?
Insoles don't cure plantar fasciitis — but they can significantly reduce the pain and the load on the inflamed fascia, which is essential for recovery. By absorbing heel strike impact and distributing pressure more evenly, CORE p.f gives the plantar fascia the relief it needs to heal. Most customers notice reduced pain within the first week of wearing them consistently.
What shoes do they work with?
CORE p.f is designed to fit a wide range of everyday shoes — trainers, walking shoes, work shoes, and casual footwear. Remove your existing sock liner first for the best fit. We don't recommend use in very flat or unsupportive shoes (like flip-flops) as these may limit the insole's effectiveness.
How quickly will I feel a difference?
Many customers notice relief from that first-step morning pain within a few days. For more significant or long-standing plantar fasciitis, allow 2–4 weeks of consistent use for the full benefit to build. Results are typically best when the insoles are worn throughout the day, not just for exercise.
Should I see a professional as well?
If your heel pain is severe, persistent, or has lasted more than a few months, we always recommend a consultation with a podiatrist or physiotherapist. StepRight clinics in Waterford and New Ross offer gait assessments and professional foot health consultations — and can advise whether CORE p.f or a fully custom orthotic is right for your specific presentation.
What if they don't work for me?
We offer a 30-day money back guarantee. If you're not satisfied within 30 days of purchase, contact us and we'll arrange a full refund — no hassle.
What's the difference between CORE p.f and CUSTOM p.f?
CORE p.f is our expertly designed pre-made insole — highly effective for the majority of plantar fasciitis sufferers. CUSTOM p.f is individually manufactured from a 3D scan of your feet, providing precisely calibrated orthotic correction. It's the right choice if you have complex biomechanical factors, very high or very flat arches, or if CORE p.f alone hasn't provided sufficient relief.
