Lacing and the Arch
In discussing lacing around the arch, a no no, I would like to show you this diagram. It shows the groups of tendons and nerve pathways that can be damaged by lacing around the arch. Especially damaging on young feet 3-up to age 19 or 20.

...Tarsal tunnel
Anatomical structure
The tarsal tunnel is found along the inner leg behind the medial malleolus.
The tarsal tunnel is made up of bone on the inside and the flexor retinaculum on the outside.
Nerve distribution
The tibial nerve, posterior tibial artery, veins, and tendons travel in a bundle along this pathway, through the tarsal tunnel.
