Aerospring Foam Construction

The Superfeet FLEXthin Insoles feature Aerospring foam, which is 3mm thick for optimal comfort. As this comfort is targeted from the heel to the toe, this underfoot cushioning helps to prevent pain caused by daily activities and walking around. The thin design also helps the insoles fit into a wider range of shoes without reducing the level of comfort provided.

MOISTUREWICK Odour Elimination

The Superfeet FLEXthin Insoles feature MOISTUREWICK technology to help eliminate odours for improved hygiene and comfort. This is particularly useful for ensuring that feet can remain as fresh and hygienic as possible, reducing odour and boosting confidence.

Enhanced Heel Protection

Specially designed to support the heel, the Superfeet FLEXthin Insoles are ideal for anybody looking to ease pressure under the heels. The heel cups are positioned to naturally absorb impact, reducing the risk of pain or damage to the heel that could arise when walking on ground that is too hard.
