Transtibial fitting is the application, with the foot selected and aligned by a prosthetist within a complete limb.
Users changing foot type during rehabilitation keep shoe size, heel height and alignment geometry when staying within one platform.
Activity progression is served by changing the element inside the foot rather than rebuilding the limb around a new outline.
Shoe fit continuity across variants matters to users who have already found footwear that works.
Stiffness selection applies where a graded element is fitted, matched to weight and activity.
Brown finish suits users for whom a darker tone gives a closer match under a sock or cosmesis.
Clinics holding platform stock benefit from variants sharing one outline, since shells and shoes carry across
