Introduction: Humans are beings who mastered bipedalism, so our feet have adapted to that special kind of movement. Gait analysis is a procedure used to evaluate human movement. It allows us to assess motion capabilities and to identify possible irregularities. In the past few decades the analysis advanced from analysing a few steps in the laboratory (confined space) to more complex gait monitoring with the use of portable sensors. Purpose: To compare the differences in foot pressure while walking with and without individually made shoe insoles. Methods: The research included 10 subjects aged 44,2 ± 19,3, who volunteered to participate in the study. We measured plantar pressure while walking. Each measurement (40 seconds) was performed on a polygon, once with and once without shoe insoles. We observed 6 variables: total minimum and maximum pressure on both feet. Results: The results of the measurements were compared and graphically presented. When comparing the minimum pressures of the left foot without the insole it presented results between 3,0–9,5 (N/cm²) and with insole between 1,7–10 (N/cm²). The maximum pressures on left foot without the insole ranged between 13,4–267,8 (N/cm²); with insole between 13,4–60 (N/cm²). Comparisons of the minimum pressure on the right foot without the insole gave us results between 0,1–7,4 (N/cm²); with insole between 0,6-9,4 (N/cm²). The maximum pressure on the right foot without the insole ranged between 16,0–38,4 (N/cm²); with insole between 11,9–57,9 (N/cm²). The highest pressures decreased with the use of insoles on the left foot in 7 out of 10 people and on the right foot in 5 out of 10 people, however, the differences were not statistically significant with a confidence interval set at p < 0,05. Discussion and conclusion: Results show that there are differences in plantar pressures when using orthopaedic insoles. The optimal relief can be achieved, when the insole is customized so that it perfectly adapts to the foot. In the future, more studies should focus on the impact of orthopaedic insoles for the same pathology. Moreover, pressure comparison between men and women, or between individually made or mass-produced insoles is needed.
