The Uvex nano shoe add in shoe deodorant uses a specially developed technology for the controlled release of active ingredients with a continuous long-term effect: antimicrobial and fungicidal active ingredients are "built in" to the shoe disinfectant in such a way that bacteria and fungi are actively and permanently eliminated. This know-how comes from chemical nanotechnology, but without the use of nanoparticles: Only approved active ingredients are used in shoe disinfection that have also been used in cosmetics for years (formaldehyde-free, phenol-free). Odour prevention: Used regularly in new shoes, Uvex nano shoe add in shoe deodorant prevents odour from developing right from the start. Unlike deodorants, which simply mask the smell of sweat, this one fights the cause of the odour: bacteria. Continuous odour control: Shoes that have already been worn become odourless again through the use of shoe deodorant. Kills athlete's foot: Filamentous or yeast fungi are among the most common causes of skin diseases on the foot ("athlete's foot"). The uvex nano shoe add in shoe deodorant kills existing fungi and prevents them from forming again. Application: Can be used on all inner shoe surfaces. Spray the inside of the shoe with uvex nano shoe add in shoe deodorant in the open air (approx. 5-10 strokes). After approx. 15 minutes, the shoes can be worn. Recommended initial treatment for heavily used shoes: three applications per week. Regular use permanently prevents odour and fungal development.
