SGL technology was developed and patented based on fifteen years’ experience with the Norwegian Olympic Team, to give active people the ultimate recovery time. The shoes counteract typical sport and stress injuries. They straighten up the heel, support the arch and provide an optimal distribution of pressure on the foot. This creates the ideal pattern of pressure for feet, calves, hips, knees and back. The deformation time of GaitLine’s polyurethane-based (PU) cushioning is 20 times that of standard ethylene-vinyl acetate (EVA). It is therefore a highly durable sole. It is well-suited for both normal and overpronated feet.
