This Invisible guarantees a pleasantly fresh feeling on the skin thanks to the use of soft, skin-flattering TENCEL™ Lyocell. The FALKE Active Breeze not only offers great wearing comfort, but is also made of a sustainable FALKE – WE CARE – yarn composition. TENCEL™ Lyocell is a biodegradable fibre obtained from sustainably grown, FSC-certified eucalyptus wood. Resulting in a material that is particularly skin-flattering and provides a high level of breathability and fast moisture transport. For this Invisible, the instep is covered, making it particularly suitable for closed shoes such as sneakers. The special heel construction and the FALKE Perfect Fit ensure optimum support, hence the Invisible does not need silicone in the heel area.
