How Insoles Change Posture
Posture does not begin at the shoulders or the lower back. It begins with how the body reads the ground it is standing on.
Can insoles change posture?
An arch-support insole holds the foot in a shape. A proprioceptive insole works differently: it stimulates the sole of the foot so the brain receives a clearer picture of the ground, and the body organises itself around that clearer picture. Posture is a brain output, and the feet are where the brain's picture of standing starts.
What proprioceptive means
Proprioception is the body's sense of where it is in space. Therapeutic Insoles use texture rather than arch support: worn inside any shoe, they work passively through normal daily movement, including while sitting, for as long as the foot stays in contact with them. Nothing to practise and nothing to remember.
Support holds a foot still. Training changes what the body does when nothing is holding it.
