Designed specifically for the low arch of the foot. The construction of the insert is adapted to the anatomy of the foot with a low vault. Thanks to its 3D construction - supporting the longitudinal vault and a deeper seating of the heel in the heel, it optimally controls the pronation of the foot with a low vault and thus provides better overall axial guidance of the body. The foot thus supported does not change its shape so much under load. Foam EVA pad under the heel for shock absorption and improved fit.
