Superfeet Flex Low - 3mm Thickness Aerospring Foam

Dynamic Full Length Comfort Insole

The Superfeet Flex Low insole has the lowest level of thickness in the Flex range with a 3mm Aerospring foam making this an ideal choice for slimmer or tighter fitting footwear. The durable topsheet foam and flexible horse-shoe heel cradle long with mild arch support provide continued comfort and support for everyday wear and specific activies such as running, cycyling and lengthy walks. 

The Aerospring foam is a viscoelastic closed cell material which works to provide the insoles with continued cushioning throughout the day. As the name 'Flex' suggests, the Flexible Heel Cradle is built from a thermoplastic horseshoe-shaped support piece, helps the foot sit into a better position and forms the foundation of the arch support in the insole. In addition the high quality top sheet is both durable and works to inhibit bacterial growth and prevent odours.

How Superfeet Work


Think of your foot and your shoe as puzzle pieces. They don’t quite fit together. Superfeet insoles are the link. They adjust your footwear’s flat, 2-dimensional midsole to your 3-dimensional foot. Ahh, a perfect fit ?

Superfeet insoles help adapt the flat midsole of your footwear to your foot. The distinct Superfeet shape helps to stabilise the foot, while the deep, structured heel cup and full-length foam provide support and comfort for every step. The Superfeet ADD/APT SYSTEM™ traces back to our start as the Sports Medicine Division of the Northwest American Podiatric Laboratory in 1974. ADD/APT encompasses the biomechanical science, technology, function and craftsmanship that adjust your footwear’s flat, 2-dimensional midsole to your 3-dimensional foot.
