Our best seller item in our C3fit series, “Arch Support Short Socks,” offers taping support that protects three arches of the foot.

There are three arches; longitudinal, lateral, and lateral vertical arch on the human sole. And our physical balance is maintained by such arches connecting three points; the roots of the big toe, little toe, and the heels. These arches play an important role in stabilizing the foot and entire body when standing, walking, running and more, and in mitigating impacts to the foot from such action.

Damaged arches fail to effectively absorb impacts and cause several problematic issues not only to the foot, but also to the entire body.

The item is also eco-friendly as it uses recycled polyester as its main material.
