で覆うかが決められ、これによって必然的にその大きさ
が決定する。Conventionally, shoes made of resin or rubber for various purposes are known. For example, shoes called underground tabi used in agricultural work and civil engineering work, short shoes that can reach the limbs of feet such as bath slippers used in bathrooms, or rain shoes worn in rainy weather, in the field Boots for various purposes, such as legs for work shoes used for agricultural work or fishing, and in some cases, special boots that can enter the body, and even shoes for sports such as skiing and skating. It has been known. Then, depending on the use of these shoes, it is decided which part of the human body to cover, and this inevitably determines the size thereof.
ところで、近年、都市部での住宅環境はますます厳しく

て押入に格納する等の手間を要する場合もある。By the way, in recent years, the housing environment in urban areas has become more and more severe, and it is not in a state where it is possible to secure as much space as possible to accommodate footwear in apartments, condominiums, and other condominiums. For large and bulky shoes such as long boots, it may not be possible to secure a dedicated storage space at the entrance or the like, and it may be necessary to wash each time after use and store them in the closet.
また、この様な雨靴や特殊な用途の作業靴は、それが如
何にも嵩張るために持ち運びが不便であり、雨の降りそ
うな日でも雨靴を携帯することができず、また、作業場
までの距離が長い場合には作業靴の持ち運びに苦労する
等の問題があった。In addition, such rain shoes and work shoes for special purposes are inconvenient to carry because they are so bulky that they cannot be carried even on a rainy day, and they cannot be carried to the workplace. When the distance is long, there is a problem that it is difficult to carry work shoes.
本発明者は、かかる観点に鑑みて鋭意工夫を行った結

Although it can be used, the shape recovery temperature can be freely set within a predetermined range, and since it can be molded like ordinary plastics, it preferably has a glass transition temperature (Tg) of 40 to 70 ° C. Urethane resins and polyisoprene resins. Of course, what is selected as the shape memory resin is determined in consideration of the relationship between the application of the manufactured shoe (in particular, the environmental temperature at the time of use) and the shape restoration temperature. When the shoe itself is required to have a predetermined flexibility, other appropriate resin or rubber such as soft vinyl chloride or synthetic rubber may be blended.
