When checking the basic alignment, verify whether the line of gravity falls through the front half of the supportive area. In order to prevent a later noise development during the orthosis’ construction, make sure to integrate a suitable toe spring. An orthosis without a toe spring makes it difficult to initiate swing phase. This means that the forefoot does not lift off the ground until very late, which causes the system joint to snap back to its original position. A loud bumping noise can occur.
