Ortholite ESD static control is the key ingredient to our anti-static designs. Ortholite foams safely discharge static build-up to the ground, protecting people against the accumulation of electrostatic charges. Unlike traditional insoles, the compression set of Ortholite insoles is less than 5% over time so the cushioning and fit never change inside the shoe. Ortholite’s open-cell PU foam is 95% to 100% breathable, allowing air to circulate in and around the insole, keeping the foot cooler inside the shoe. The unique open-cell structure of Ortholite insoles creates a moisture management system, helping to move moisture away from the foot to provide a cooler, drier, healthier shoe environment. A patented salt-based antimicrobial is added to all Ortholite foams to fight against the presence of fungus, bacteria and odour. The antimicrobial inhibits the build-up of the bacterial fungi often associated with the cause of odour.
