Ergon a.s. is a longstanding manufacturer of various types of individual special orthopedic INSOLEs and now of semi-products for individual tailored manufacture. All types of insoles are used to compensate minor disorders of the sole of the foot, correct poor foot posture, and reduce the load on painful spots. Many types of materials are available for this manufacture, such as artificial cork, pedilin, polyform, and natural leather. The prosthetic engineer will recommend a type of insole based on the referral letter from a specialist physician (orthopedic or rehabilitation).
