Viscoelastic heel cushion for equalizing misalignment ViscoHeel K If the legs are misaligned with the center of the body, either in the form of knock knees or bandy legs, the position of the heels also becomes tilted, which leads to one-sided loading. The ViscoHeel K heel cushion can correct this with ease. It is raised at the side and can be fitted into the shoe to even out a tilted position. This reduces pressure peaks, protects joints, and gently cushions the heel. Raised at the side A perfect fit in closed shoes Gentle on your skin
