The CALCA line combines effective pressure relief in the heel area with longitudinal arch support. Best suited to treat frequently occurring, painful heel complaints, the CALCA II, the CALCA PRO X and the CALCA PRO X XL offer optimal care for pain-free walking. The CALCA line’s centrepiece is the orthotic shell made from glass fiber composite materials we developed and produce by ourselves. Due to its thermoplastic properties, the shells can be adapted to the user simply and uniquely. The heel relief provided in the orthotic shell is orientated on the plantar fascia’s anatomical location and runs to the foot’s longitudinal arch. This relieves the plantar structures and promotes positive therapy progression. High-quality materials which meet PERPEDES’ quality demands are used in the CALCA line. The foot orthotic’s components are perfectly attuned with each other.
