Brandon, should you have a correctly diagnosed forefoot varus you should benefit from the issue of an orthotic device. This would be dependant on whether your forefoot compensates by pronation or 1st ray plantarflexion. Ultimately you would find some benefit in a 2nd - 5th metatarsal bar leaving the 1st metarsarsal free to plantarflex.

Orthotic management of intrinsic (structural) foot deformities
These structural variations result in predictable compensations. The compensations may lead to pain and dysfunction. In each case, an orthosis can support the deformity and eliminate the need for compensation (Tiberio, 1988).

Prevalence of structural foot deformities:
Rodgers (1995, p.307) reports on research by Garbalosa and colleagues (1994), who investigated 234 asymptomatic feet and found the following forefoot-rearfoot relationships:
Aligned: 4.6 percent
Forefoot varus: 86.7 percent
Forefoot valgus: 8.8 percent
