|Forefoot Platform- A flat plane created across
the metatarsal heads on a positive representation of the foot. At
its proximal aspect, the forefoot platform blends into the plantar aspect
of the foot at the metatarsal shafts, and is constructed so that
the platform extends proximal to the proximal aspect of the first and fifth
metatarsal heads. The distal leading edge of the orthotic device either
meets the plane of the platform, or extends onto the plane of the platform.
The leading edge of the finished device ends just proximal to the first
and fifth metatarsal heads.
