Functional hallux limitus has been recently described as an etiologic factor in postural complaints. Eversion of the rearfoot has been theoretically linked to decreased hallux dorsiflexion, although there have been no scientific studies on this subject to date. This study was undertaken to investigate the relationship between rearfoot eversion and hallux dorsiflexion; the results show that hallux dorsiflexion is decreased with rearfoot eversion in a static setting.
