2 . The wearable device of claim 1 , wherein the pressure sensing unit includes a flexible cushion having a fluid therein and a fluid passage connecting an internal space of the flexible cushion to the acupressure unit, and
wherein the acupressure unit is arranged at an inner portion of the shoe with respect to a user's ankle bone and the acupressure unit includes an acupressure projection connected with the fluid passage and projectable when the fluid flows from the internal space to the acupressure unit.

3 . The wearable device of claim 1 , wherein the acupressure projection is arranged to be adjacent to a circumference of the ankle bone or under the ankle bone.

4 . The wearable device of claim 1 , further comprising:
a curvature measurer arrangeable at a lateral surface of the user's ankle; and a control unit provided to sense curvature measured by the curvature measurer and control the acupressure projection to be positioned at a point having a large curvature.

5 . The wearable device of claim 1 , further comprising:
a battery to supply electric power; and a wireless charging coil provided in the base to charge the battery when placed in an external electromagnetic field.

6 . The wearable device of claim 1 , further comprising:
a fixing unit coupled to an ankle portion of the shoe and coupled to the acupressure unit by a hinge; an acupressure projection projected from a first side of the acupressure unit toward a user's ankle; and a wire having one end coupled to a side of the acupressure unit opposite the first side and another end coupled to the pressure sensing unit, wherein the wire is configured to receive a tensile force when the user is walking and the acupressure unit is rotated on the hinge, and the acupressure projection is pressed toward the user's ankle.

7 . The wearable device of claim 1 , further comprising a fixing unit coupled to a heel portion of the shoe, and
a pair of acupressure units provided at opposite sides of the fixing unit, respectively, each acupressure projection being provided between a user's ankle bone and a user's Achilles tendon.

8 . The wearable device of claim 1 , wherein the pressure sensing unit is provided in plurality,
wherein the acupressure unit is provided in plurality, each of the plurality of acupressure units is associated with a corresponding one of the pressure sensing units, each of the plurality of acupressure units includes an acupressure projection, and wherein the wearable device further comprises a control unit to control the plurality of the acupressure units such that the acupressure projections are selectively controlled based on the pressure sensed by the corresponding pressure sensing unit.

9 . The wearable device of claim 8 , wherein a plurality of acupressure modules are defined by the acupressure units and corresponding pressure sensing units,
wherein the control unit is configured to control at least one of the acupressure modules such that the acupressure projection is projected, when the order of the pressure variation sensed by the pressure sensing unit is different from a preset order of pressure variation, and wherein the acupressure modules are arranged along a longitudinal direction of the base.

10 . The wearable device of claim 1 , further comprising:
a battery to supply electric power to the acupressure unit; and a control unit, wherein the acupressure unit is an electroactive polymer having a variable profile when a voltage is applied thereto, and wherein the control unit is configured to:
apply a first-leveled voltage corresponding to a first height variation of the acupressure unit to the acupressure unit,
