1 Background of it: Handmade Cloth Shoe of Many-layer Tread of "Tugada Brand" was made of tread from cotton culico of 30 or so layers through handwork stitch, of upper from high grade cloth like "Canonicals Wool", and "Spring Breese Wool" after 10 or more working procedures of shoe-making. The most notable feature for this kind of shoes is air free and sweat absorbable. Wearing them may facilitate the stretch and adaptability of feet to their surroundings. Therefore, care to one's foot may be realized. Whole production procedure for this shoe is free from any chemical substance, and it belongs to one thoroughly natural production manner. These shoes have combined the skill, comfortable, and air free to one purpose of health care with character of cold-proof in winter and heat-insulation in summer.
