There's nothing standard about the levels of safety.
The lower, shoe like version of the Constans is created from a high quality full grain leather upper and nappa leather lining. It's also been exclusively developed for semiorthopedic adjustments especially where customised in-soles are required. Even when customised and adjusted, the shoe still exceeds European Standards of safety.
