Purpose The aim of this study was to investigate the difference in ankle stability according to the height of the worn elastic ankle protector. Methods The subjects of this were 17 healthy subjects. After wearing a lowheight elastic ankle protector and a highelastic ankle protector, plantar pressure was measured and analyzed during the gait cycle. Results As a result of the study, there was no statistical significance in the six areas of the forefoot, and when walking with a highelastic ankle protector, there was a statistically significant difference in R1, R3, and R4 among the four areas of the hind foot (p<0.05). Conclusion A high ankle protector can help stabilize the ankle joint when walking, and it can help normal gait by increasing the pressure on the sole of the foot.
