RE-INFORCEMENT OF THE STOCKING
in those areas of the foot which receiveBecause of the structure of the human foot, and the stresses on the bones of the foot, manufacturers—during the making of the feet of Women’s stockings—knit in an extra thread called a “splicing” or reinforcing thread. This is placed in those parts of the stocking foot which rub most against the shoe when walking or standing, that is: the back of the heel, the sole, and the toe, and by the use of the splicing thread, these points are considerably strengthened.
the most wear
The foot is a shock-absorbing bridge-like structure which supports the body. The stresses on the bones and ligaments of the foot amount, in engineering terms, to 250 tons for every mile walked. Fortunately for the stocking manufacturer, the weight of the foot—due to its architecture—does not fall on any single bone. When standing, half the weight of the body goes down each leg, and falls squarely on the talus, being a wedge-shaped chunky bone at the ankle. This bone throws half the leg weight of the body to the heel; the other half is distributed among five slender bones called metatarsals. These bones run like fingers down the forepart of the foot, and when walking or running, all the weight is thrown forward on to these. Should any of these critical bones become enlarged, or one of the five shirk its share of weight, an extra burden is placed on the others, and in that case, the weight being unevenly distributed, unequal wear would result, as it will be understood that no manufacturer can cater for individual foot requirements. It has been found that in the case of a person weighing 120 lbs. the weight distribution when standing is:-
|To each foot 60 lbs., divided as follows:-|
|To each heel||30 lbs.|
|To the first metatarsal (behind the big toe)||10 ''|
|To the other four metatarsals 5 lbs. each||20 ''|
