Replaceable pressure-reducing breathable insole for a rehabilitation boot

A replaceable pressure-reducing breathable insole for a rehabilitation boot comprising:

• a body having
• a top surface;
• a bottom surface;
• and
• a side wall annularly formed between the top surface and the bottom surface of the body to form an outer contour of the body;
• multiple decompression protrusions disposed on and protruded from the bottom surface of the body at spaced intervals, configured to abut against a bottom of the rehabilitation boot to form multiple airways between the bottom of the rehabilitation boot and the bottom surface of the body, being elastic, and each one of the decompression protrusions having
• an inclined face obliquely formed on a front side of the decompression protrusion and configured to cooperate with a moving direction of the rehabilitation boot to increase a contacting area to reduce pressure;
• and
• a curved face formed on a rear side of the decompression protrusion, formed with the inclined face, and configured to abut against the bottom of the rehabilitation boot to allow the decompression protrusion to elastically deform;
• and
• multiple breathable holes formed through the top surface and the bottom surface of the body at spaced intervals and communicating with the airways between the bottom of the rehabilitation boot and the bottom surface of the body.
