The uvex tune-up insoles have been developed to enhance individual comfort for various foot types. Each foot has a longitudinal and a transverse arch that distribute weight and act as natural cushioning elements. High or frequent loads, weakened muscles and ligaments, or even congenital deficiencies can affect the shape of the foot's longitudinal and transverse arches. This can lead to various misalignments such as flat feet (lowered longitudinal arch), high arches (pronounced longitudinal arch), or splayed feet (lowered transverse arch), which can subsequently cause pain. By using the tune-up insoles, the transverse arch can be supported, and the contact area can be increased, leading to better pressure distribution. This can enhance wearing comfort and reduce pain and fatigue, while the protective function of safety shoes remains unaffected.
