S3F® Active process with long-lasting triple protection against: Bacteria, fungi and odours.
In a partnership with a laboratory specialised in foot care, the JLF Group has developed an exclusive solution: the 3 Function Solution (S3F®). This solution, which features an active process with long-lasting triple protection (against bacteria, fungi and odours), helps ensure optimal foot hygiene and freshness. This S3F® solution is to be applied on the surface of most of the JLF Group’s hygiene insoles. “S3F®” identifies those products that prevent the spread of odours caused by athlete’s foot and bacteria. These inconveniences are familiar to those who wear closed shoes such as safety shoes and work boots.
