Development of prosthetic feet for high-heeled shoes
Wearing high heels (HH) with a prosthetic leg requires plantar flexion, the same as for a natural foot. However, the alignment of the whole limb is altered and the walking pattern therefore affected. Current prosthetic feet avaialable for different HH focus on dorsiflexion oreientation without adjusting insoles.
A 5-step process of development is initiated for accurate insole shape.
- Establishes there is no relationship between insole shape and shoe size for given HH
- Verifies as similar HH exhibit same insole shape, irrespective of shoe size
- Findings mathematically defined
- Transferred findings to physical show sole.
- Prototyping; 3 Indvidual given 3 testing feet for 3 HH of their choosing.
Participants found they did not require more attention when walking outside on HH, except for occasional uneven surfaces. The protoype shows great promise; further development and testing is needed before mass production.
