Omersub interchangeable foot pocket has been designed and developed internally by our technicians and it is manufactured with newest rubber compression molding technologies existing today. The internal geometry of the foot pocket, thanks to the great experience of Beta Tools in the production of safety shoes, has been ergonomically designed to fit with total comfort. The foot pocket is produced with natural rubber in two different stiffness compounds throughout the different sections of the pocket to maximize the efficiency of the stroke without compromising comfort.
