**6. Conclusions**

Wearing shoes with heels over 6 cm may produce a valgus and abduction increase in PPH movement. This abduction is specifically detected in the development of HAV pathology. Future cohort studies will be required to clarify the time period that is needed to develop HAV pathology related to high-heeled shoes.
