Description
Formthotics Sport ShockStop – Plantar Fasciitis Arch Support Insoles
Formthotics Sport ShockStop Full Length is a dual-density running insole built specifically for high-impact activity. The ShockStop layer absorbs and disperses impact energy through the heel and forefoot, reducing fatigue and stress through the lower limb — making it one of the go-to plantar fasciitis arch support insoles for runners and athletes managing heel pain.
Why Runners & Athletes Use ShockStop
- Dual-Density Cushioning – a firmer base layer paired with a softer ShockStop impact layer at the heel and forefoot
- Full-Length Arch Support – consistent support through the gait cycle, not just at the heel
- Thermomouldable – can be heat-moulded in-clinic for a closer, more personalised fit, or worn straight from the pack
- NZ-Made, Clinically Used – the same material trusted by podiatrists and physiotherapists across Australia
Who These Insoles Are For
- Runners and athletes managing plantar fasciitis or heel pain during training
- Shin splint prevention and support for high-mileage weeks
- General running-related foot fatigue on long or repeated sessions
- Anyone needing extra shock absorption in athletic or training footwear
Sizing
Available XXS–XL to fit most athletic and training footwear. Trim guides are marked on the insole for a precise fit.
FAQ
Will these help with my plantar fasciitis?
Many runners use ShockStop to reduce heel-strike impact and manage discomfort during training. Every case is different, so it's worth discussing persistent heel pain with your podiatrist alongside using supportive insoles.
How does thermomoulding work?
Your podiatrist or physio can heat-mould the insole in-clinic for a closer, more personalised fit — or you can wear them straight from the pack without moulding.
I don't run – is this still right for me?
ShockStop is built for high-impact activity specifically. For everyday, non-running arch support, Trekker Full Length may be a better fit.
What's the difference between this and a standard Formthotics insole?
The dual-density ShockStop layer is the key difference — it adds an extra impact-absorbing layer at the heel and forefoot specifically for high-impact use, beyond what a standard single-density Formthotic offers.
