PROBLEM TO BE SOLVED: To provide foot thermal insulation shoes capable of allowing an acoustic vibration to work not only on soles but also in wider ranges of feet.SOLUTION: Foot thermal insulation shoes 2 are to be put on feet 91 of a user and placed on a foot base 4 for generating an acoustic vibration, so as to massage the feet 91 of the user by the acoustic vibration. Each shoe is formed to have a footwear shape with a dual structure having an inner wall and an outer wall with the use of a flexible sheet. A liquid storage chamber for storing a liquid is formed between the inner wall and the outer wall. Multiple joint parts to partially joint the inner wall and the outer wall are formed to allow the liquid storage chamber not to be divided but to be connected as a single body. The liquid is sealed in the liquid storage chamber. |
