Bio-functional Socks

Aging makes skin more susceptible to dryness, even in a relatively warm and humid environment like Hong Kong. Dry skin on the feet, often experienced by the elderly especially during the winter months, can lead to roughness, peeling, cracking or scaling.

To prevent or improve these conditions, special bio-functional socks were designed. Wearer trials were conducted in a number of elderly centres in Hong Kong.


The developed socks are based on an innovative design which provides improved ergonomic structure and effective functional treatment. The socks are able to:

  • buffer moisture in the foot-sock microclimate environment;
  • prevent moisture loss; and
  • provide sensations of enhanced comfort, softness and smoothness for the wearer.

Industry benefit

The socks have a good cost-performance ratio since no special facilities are required for mass production. The feedback from the wearer trials in elderly centres showed that the socks function well in terms of moisture prevention.

Technological breakthrough

The bio-functional material of the socks, which increases air permeability and at the same time reduces water vapor permeability, provides the desired moisturizing performance.

Licensing Details

A non-exclusive licence covers the knowhow of the mechanism and production of the bio-functional socks.
