INTRODUCTION: In our society, it is observed an increasing number of models, colors, styles, heights and types of high heels. OBJECTIVE: To evaluate whether the use of high heel shoes results in postural changes, based on a set of variables measured through computerized photogrammetry. METHODS: Twenty individuals who often used high heels (group 1) and 20 individuals who only used high heels sporadically (group 2) were photographed in the frontal and sagittal planes at three conditions: a) without using footwear; b) using stiletto heels; and c) using high platform heels. These photographs were randomized and analyzed by a blinded examiner, by means of photogrammetry. Statistical analysis was performed, using a 2x3 factorial analysis of variance to compare the frequency of high heel use with the type of shoe, at the 5% significance level. RESULTS: Only the head protrusion angle showed a difference between groups 1 and 2 (p<0.01). The effect of the type of shoe observed in the alignment of the right knee, which only showed a difference between stiletto heels and barefoot (p=0.03). For the tibiotarsal angle variable, the effect was also observed for all types of footwear. The other angles evaluated did not present any differences regarding the frequency of high heel use and the types of shoe. CONCLUSIONS: The frequency and type of high heel practically did not change the static posture evaluated by photogrammetry.
