As a result, the transition from weight support to weight transfer is smooth.
It's done. Furthermore, the second member and the third member are separated from each other.
And the rigidity against twisting between them is reduced.
Therefore, when the weight moves from the outside of the foot to the inside,
It is possible to absorb the twist applied to the foot,
The transition from weight support to weight transfer is smooth
To be done. Furthermore, only the first member is used as the first stage
You can improve the symptoms by using the
Since the upper surface is a horizontal plane,
From the time of heavy movement to the time of leaving the bed, the weight-bearing route is the center of the toe.
It is possible to prevent the hallux valgus by passing through.
