Product Description

Slimflex Comfort Orthotic Insoles – Low-Density

Support for Flat Feet and Sensitive Foot Types

For those with flat feet or delicate foot structures, even moderate pressure and misalignment can cause significant discomfort. The right orthotic insole doesn’t just cushion the foot – it supports, stabilises and encourages better movement.

Lightweight, low-density and anatomically shaped, this insole offers gentle but effective support for those who need help maintaining proper foot posture – without the bulk or rigidity of more aggressive orthotics.

Gentle Support, Smart Design

Research backed Slimflex Comfort insoles are widely trusted by UK podiatrists and physiotherapists, especially in NHS clinics, where a balance of affordability, ease of use and effectiveness is essential. The low-density EVA foam provides soft, responsive support – ideal for delicate feet, older adults, children and anyone who finds firmer insoles too harsh or intrusive.

The 3/4 length design offers support through the heel and arch while allowing full flexibility at the forefoot. It’s a subtle but powerful solution for everyday use - with added comfort from a brushed nylon top cover that helps reduce friction and moisture build-up.

  • Low-Density EVA for Delicate Feet: Perfect for people with thin or sensitive skin, fat pad atrophy or early-stage

Arch Support Insoles

Orthotic Insoles – When and Why to Use Them

Support for Arch Problems and Over-Pronation

Orthotic insoles with arch support help correct over-pronation (when the foot rolls inward too much). By keeping your feet properly aligned, they can relieve pressure on the plantar fascia and improve your overall posture. These insoles also help prevent both flat feet (pronation) and outward rolling (supination).

Designed for Flat Feet

If you have flat feet, orthotic insoles help by filling the gap between your foot and the inside of your shoe. A contoured 3/4 length design is ideal, as it supports the arch and fits easily into narrower or tight-fitting footwear without crowding the toes.

Customisable for Individual Needs

Some people may benefit from custom-made insoles that are shaped to their exact foot structure and walking style. Slimflex Comfort insoles offer a high level of customisation – meaning they can be adapted to suit many foot conditions. For even more specific modifications, you can combine them with Podotech components.

Ideal for Quick, Chairside Solutions

Slimflex Comfort is a great choice when fast treatment is needed. They’re perfect for use in clinics where podiatrists or physiotherapists need to fit and adjust insoles on the spot. These insoles are ready to wear but can be quickly modified to suit individual biomechanical needs.
