Shoes have to be functional and in everyday use they need to cope with the mechanical challenges of walking, not just in the case of sports shoes or orthopaedic footwear, but generally. Shoes come under great stress and it is not uncommon for them to include high-tech concepts for support, cushioning or in terms of their breathability. At the same time they have to look right. Seams are often an important element of shoe design. With sewing threads from AMANN there are no limits in that respect.
