The impression of a normal foot shows that the plant does not rest on the floor across its surface. The contact points are:
Anteromedial support corresponding to the 1 st metatarsal head, covered his sesamoid.
Anteroexterno support, which is the head of the 4th and 5th metatarsal. Between these two supports is a set of soft tissue that conceals the head of the other metatarsals, whose support is less important.
A further support that corresponds to the bottom and back of the calcaneus. The back support (heel) is linked to earlier support for a foreign band more or less wide, while the inside is a "gap" hollow inside. We see that this impression that there is:
An external longitudinal plantar arch, apparently flat for consideration, as it is padded by muscle layers.
An internal longitudinal arch, which lies above the ground and is structured as a bridge between the support post and support anterinterno.
