The Vasyli Forefoot Valgus Wedge address specific problems, such as a forefoot valgus abnormality. If the foot has a forefoot valgus abnormality, measure the angle where the plantar plane of the forefoot is everted relative to the plantar plane of the rearfoot (ground) when the subtalar joint is in neutral. If the angle of forefoot valgus is 6 degrees, the forefoot should be posted at 6 degrees under the plantar metatarsal area with the thickest part of the wedge proximal to the fifth metatarsal head.
