The 3Feet High Arch insoles from Sidas are ideal for everyday and leisure use. Designed specifically for high arch feet, the insoles provide anatomical construction which adapts to the aforementioned high arch feet to improve both comfort and performance. Extreme cushioning is provided by both a forefoot pad as well as a large gel pad. Located at the rear of the insole is a large PU gel pad, for further cushioning and arch support. This is designed to absorb shock and lessen the impact placed upon your knees and joints by evenly spreading out the weight as you move. An EVA shell is moulded in the form of a high arch shape to provide the much-needed support whilst retaining comfort without sacrificing performance. Within the insoles are perforations which improve breathability and ventilation. The perforations allow cool air to enter, and warm air to exit to ensure your feet remain as cool and composed as possible. This also helps to eliminate the build-up of excess sweat and moisture, preventing any discomfort or irritation in the process. A bamboo top cover has been added to the insole to offer anti-bacterial properties to reduce any odour causing microbes.
