The invention avoids this problem, since the disposable overshoe can be kept in stock in a relatively small number of sizes and sold to the bowlers, who they can use their street shoes or in the event that the bowler’s street shoe does not have a suitable shape for bowling, can put on the stocking directly on the puss ο

The number of sizes in stock can be limited, since there are only a few large sizes available for both adult and child shoe sizes is possible due to the heat sump properties the foil, which makes it possible for the cone overshoe to fit the size of street shoes over a wide area Can be shrunk. The disposable shoe is also useful for wearing over street shoes for protection in bad weather, the heat-shrinkable film can be sufficiently strong and wear characteristics to maintain their usability during prolonged use.

The disposable overshoes are designed so that they can both be folded up and stacked in the smallest of spaces can and for a sales transaction by a sales
