PROBLEM TO BE SOLVED: To provide an insole which can increase a bracing force of the foot by putting on a footwear and moving the toe.SOLUTION: An insole 1 is for a footwear, such as sneakers, slippers or sandals which are normally used. A part where the thumb is rested is provided with a parallel cut-off part 3 by cutting off an end part 5 of the insole 1 almost in parallel so that the toe can be bent from the root and a diagonally cut-off part 4 by cutting off a part where the second finger to the fifth finger are rested almost diagonally. A part between the thumb and the second finger is left without being cut off and, on its top surface, an inter-finger pad 2 having thickness that is thoroughly formed by an elastic member is pasted and provided. Thus, a bracing force of the foot that allows exercise bending the toe is increased.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】 履いて足指を動かすことにより足の踏ん張り力を向上させることができる中敷きを提供することを目的としている。【解決手段】 履物、例えば普段使用しているスニーカーやスリッパ、サンダル等の足の形状を持った中敷き1で、該中敷き1の先端部5を足指が付け根から曲げられるように、親指の乗る部分は、略平行に切り落として、平行切り落とし部3を設け、第2指から第5指の乗る部分は略斜めに切り落として、斜め切り落とし部4を設け、親指と第2指の間の部分は、切り落とさずに残して、その上面に、全体が弾力性のある部材で形成された高さのある指間パッド2を貼り付けて設け、足指の折り曲げる運動ができる足の踏ん張り力を向上させる中敷き。【選択図】図2
