The uvex tune-up insoles were developed to increase individual comfort for different foot types. Every foot has a longitudinal and a transverse arch, which distribute the weight force and act as natural cushioning elements. High or frequent loads, weakened muscles and ligaments, or even congenital insufficiencies can affect the shape of the longitudinal and transverse arch of the foot. This can result in various deformities such as flat feet (lowered longitudinal arch), hollow feet (pronounced longitudinal arch) or splay feet (lowered transverse arch), which can subsequently also lead to pain. By using tune-up insoles, the transverse arch can be supported and the contact area increased, which leads to a better distribution of pressure. The wearing comfort can thus be increased and pain and fatigue reduced - the protective effect of the safety shoes is not impaired.
