Understanding Flat Feet
Flat feet — also known as fallen arches or overpronation — occur when the arch of the foot collapses, causing the entire sole to make contact with the ground. It's one of the most common foot conditions, affecting around 30% of the population. While many people with flat feet experience no discomfort, others suffer from foot pain, knee pain, shin splints, and lower back ache.
The good news? The right insoles can make a significant difference — providing the arch support your feet need to function properly and reducing strain throughout your body.
What to Look for in Insoles for Flat Feet
1. Arch Support
This is the most critical feature. Look for insoles with a firm, structured arch that fills the gap between your foot and the ground. Soft, cushioned insoles without arch support may feel comfortable initially but won't correct overpronation or relieve associated pain. At Aetrex we have created the perfect options whatever type of feet and arches you may have.
2. Deep Heel Cup
A deep heel cup cradles the heel and helps realign the foot into a more neutral position. This reduces the inward rolling motion (overpronation) that flat feet cause and distributes pressure more evenly across the foot. L620 from Aetrex is designed speficially for this type of foot.
3. Firm vs. Soft Materials
For flat feet, a semi-rigid or rigid orthotic is generally more effective than a purely cushioned one. The structure helps control motion and support the arch. Aetrex insoles offer the perfect support for your feet, while giving the flexibility of natural movement.
4. Metatarsal Support
Many people with flat feet also experience pressure under the ball of the foot. Insoles with metatarsal support help distribute this pressure and reduce forefoot pain. The L625 orthotic is specifically designed for this type of foot, offering all day comfort whatever you are doing.
5. Correct Sizing
Insoles that are too large or too small won't provide proper support. Always check the sizing guide.
Flat Feet vs. Overpronation: What's the Difference?
Flat feet describe the shape of your foot — a low or absent arch. Overpronation describes how your foot moves — rolling inward excessively during walking or running. Most people with flat feet overpronate, but not all overpronators have flat feet. Insoles designed for flat feet typically address both issues. Aetrex specialise in these type of orthotics.
Which Activities Need Insoles Most?
If you have flat feet, insoles are particularly important during:
- Running and sport — High-impact activities amplify the effects of overpronation, increasing injury risk.
- Long periods of standing — Jobs that require standing all day put sustained pressure on unsupported arches.
- Walking on hard surfaces — Concrete and tile offer no natural cushioning, making arch support essential.
Custom Orthotics vs. Over-the-Counter Insoles
Aetrex are the gold standard for severe flat feet or complex biomechanical issues. Aetrex — use advanced technology to deliver excellent support at a fraction of the cost of hand made orthotics. Aetrex's orthotics, for example, are personalised based on a foot scan and offer a level of customisation previously only available through podiatrists.
Tips for Getting Started
- Get a foot scan or assessment to understand your arch type and gait.
- Replace insoles every 12 months, or sooner if you're very active.
- Allow a short break-in period — your feet may need a week or two to adjust to proper support.
- Pair insoles with supportive footwear for best results.
Choosing the right insoles for flat feet doesn't have to be complicated. Focus on structured arch support, a deep heel cup, and the right fit for your activity level — and your feet (and the rest of your body) will thank you.
