ORTHOLITE®: Engineered from open cell polyurethane, Ortholite soles retain 95% of their cushioning after one year of use, whereas ordinary soles lose 70% of their cushioning over the same time period.

The Ortholite® sole is light and breathable. The air circulates, to help evacuate heat and moisture to keep the feet dry. The environmentally-friendly biocide treatment is antimicrobial and creates a healthier environment for the feet. The advantages of Ortholite® Open-Cell Technology are:

Carbon fibre heating elements
Lining: 100% polyester
Base: Ortholite®
EVA: The moulded EVA foam insert is particularly flexible. It helps improve shock absorption and lightness.
