Abstract

A measurement device for shoe fitting evaluation is disclosed. The measurement device for shoe fitting evaluation includes a last insertable into a shoe, a pressure measurement unit configured to measure a wearing pressure on a top surface of a foot of the last, and a gap measurement unit configured to measure a gap between an end portion of the last and an end portion of the shoe. The last includes a main body portion and a variable portion. The variable portion is changeable in its shape, its weight, or its position with respect to the main body portion.

Claims (15)

1 . A measurement device for shoe fitting evaluation comprising:

a last insertable into a shoe, a top surface of a foot of the last being a surface region configured to be in contact with an upper inner surface of the shoe with the last inserted into the shoe;

a pressure measurement unit configured to measure a wearing pressure applied on the top surface of the foot of the last from an upper of the shoe in a state where the last is inserted into the shoe; and

a gap measurement unit configured to measure at least one of a gap between a front end portion of the last and an inner front end portion of the shoe and a gap between a rear end portion of the last and an inner rear end portion of the shoe,

wherein

the last comprises a main body portion including a heel portion of the last and a position variable portion including an ankle portion,

a position of the position variable portion with respect to the main body portion is changeable,

the position variable portion is configured to be fixed at different set positions with respect to the main body, and

the pressure measurement unit is configured to measure the wearing pressure applied on the top surface of the foot of the last at the different set positions of the position variable portion with respect to the main body in a state where the shoe is worn by the last.

2 . The measurement device for shoe fitting evaluation according to claim 1 , wherein

the position variable portion includes a front portion of the last, an angle of each of the ankle portion and the front portion with respect to the main body portion is changeable, and each of the ankle portion and the front portion is configured to be fixed at a changed angle.

3 . The measurement device for shoe fitting evaluation according to claim 1 , wherein the pressure measurement unit has a pressure sensor disposed on the top surface of the foot of the last.

4 . The measurement device for shoe fitting evaluation according to claim 1 , wherein the position variable portion is configured to be fixed at the different set portions with respect to the main body via a gear, a pawl, or a ratchet mechanism.

5 . The measurement device for shoe fitting evaluation according to claim 1 , further comprising

a bottom surface pressure measurement unit that has a plurality of pressure sensors, wherein the plurality of pressure sensors are provided on a bottom surface of the foot of the last at a toe, a tread, an arch, and a heel.
