The invention discloses a shoe, which comprises a vamp, wherein a thermoplastic sheet-shaped framework is embedded in the vamp, the bottom end of the framework is fixedly connected with the bottom of the vamp, the framework extends at least in the height direction of the shoe to support the vamp, and the degree of shrinkage or expansion of the vamp is changed through thermoplastic deformation of the framework. In the invention, a thermoplastic sheet-shaped framework is embedded in the vamp of the shoe, and the bottom end of the framework is fixedly connected with the bottom of the vamp. The armature extends at least in the height direction of the shoe to support the upper, the extent of the tightening or opening of the upper being altered by thermoplastic deformation of the armature. The shoes can better adapt to the use requirements of different customers, so that the wearing sense of the shoes is more comfortable. When the width of the shoe is adjusted, the framework is heated and softened firstly, then the feet extend into the shoe, the shoe is propped up to a proper shape, and the shoe suitable for the feet with different sizes can be obtained after the framework is cooled and shaped.
