AFS Slim Sport is a thinner product than AFS Premier. It is only 2mm high and will fit into Soccer-, narrow running-, Ski-, Casual and Sneaker shoes. The Dynamic support will give you an instant feel of comfort in any shoe you use them in. It is also based on the worldwide patent from Ortolab, Scandinavia’s leading manufacturer of orthopedic footbeds. The Dynamic support helps preventing the arches from collapsing, giving the foot a lively feeling.
