Abstract: A pressure fixing device applied to a shoe is disclosed. The pressure fixing device includes an inflatable shoe tongue, a first air pump and a control module. The control module drives the air to flow out of the inflatable shoe tongue according to a second enabling signal so that the inflatable shoe tongue tends to shrunk and moves toward the wear space to attach to a user's instep. The control module drives the first air pump to pump the air flowing into the inflatable shoe tongue according to a first enabling signal, so that the inflatable shoe tongue tends to expand due to the air inflated and moves away from the wear space to enlarge the opening, by which the user can wear or take off the shoe easily.
