Abstract

The invention provides a shoe sole, and particularly relates to a shoe sole used for a diabetic patient and a slipper made of the shoe sole. The shoe sole comprises a foot-shaped bottom layer; an airbag layer used for bearing weights of different diabetic patients is arranged in the bottom layer; the bottom layer has the length from a heel area to a toe area and is provided with a cavity used for containing the airbag layer; the lateral wall of the airbag layer is provided with a first air port used for inflation or deflation; the lateral wall of the bottom layer is provided with a second air port corresponding to the first air port and used for transmitting air into the first air port. The slipper comprises a first-part vamp fixed to one side of the shoe sole and a second-part vamp fixed to the other opposite side of the shoe sole, and the first-part vamp and the second-part vamp are movably connected to form a whole vamp, wherein the distance between the bottom layer and the whole vamp can be adjusted. The shoe sole and the slipper enable the diabetic patient to feel comfortable, and can be used by the diabetic patients with different weights and different foot shapes conveniently.
