Professional practitioners who are required to stand for long periods of time frequently complain about vein-related symptoms. Compression stocking are effective for vein-related symptoms, but there is not enough evidence on the effect of the length of compression stockings for nursing students. To compare oedema, pain, and satisfaction according to different lengths of compression stockings worn by female nursing students. This study was conducted as a randomized clinical trial. The participants included 20 female nursing students in their first semester of clinical practice training. Compression stockings with 25–32 mmHg pressure were used in the study; the participants were divided into two groups based on the length of compression stocking: knee length and thigh length. Differences between groups regarding pain, oedema, and satisfaction were analysed using t-tests, paired t-tests, and Mann–Whitney U tests, when appropriate. There were no significant differences in pain, oedema, and satisfaction between the two groups. However, pain in right legs of the thigh-length stocking group significantly increased after clinical training shift compared with that before the shift (t = −2.377, p = 0.041). Both groups reported high satisfaction. There were no differences in pain, oedema, and satisfaction in both legs based on the length of compression stockings, but side effects appeared in participants wearing the thigh-length stockings; nevertheless, satisfaction was high in both groups. It may be important to suggest nursing students to wear knee-length compression stockings during clinical practice training.
