Letter to Editor Gait characteristics when walking with rounded soft sole shoes Dear Editor, I read with great interest the article by Demura et al. “Gait characteristics when walking with rounded soft sole shoes” [1] in which the walking kinematics of three different shoe conditions have been investigated. Although the authors have performed an interesting research, their data reporting method in the result section of the article confuses me. While authors in Section 2.4.2 (kinematics) and also Section 3.2 (kinematics data) refer the reader to figures 5-1, 5-2 and 5-3, surprisingly all of these figures are missing in the article. At the end of the Section 3.2 (kinematics data), authors refer to figures 6-1, 6-2 and 6-3. The figures are present, but figures 6-2 and 6-3 are identical and figure 6-2 does not present the knee joint angle as the legend indicates. My major concern, however, is not the mentioned errors but the reporting method of ankle kinematics. I wonder why ankle angles in figure 6-3 and also table 2 have been presented in negative values only. What does a negative dorsiflexion angle mean? How is it possible to differentiate between plantarflexion and dorsiflexion during the gait cycle? Since the joint angles are the main outcome

measures of this article, in order to have a better understanding and interpretation of the results, I would encourage authors to clarify their method and its advantages compared to the standard method. Conflict of interest statement None. Reference [1] Demura T, Demura S, Yamaji S, Yamada T, Kitabayashi T. Gait characteristics when walking with rounded soft sole shoes. Foot 2012;22(1):18–23.
