The Inefficacy of Cushioned Column Footwear in Preventing Ankle
Inversion Sprains during Basketball Participation

Hashish, J Nov Physiother 2015, 5:2 (full text)

In basketball, inversion sprains are likely caused by one of three primary factors: (i) high loading rates; (ii) landing
in a supinated or plantar flexed ankle position; and (iii) excessive frontal plane displacement of the center of mass. In
effort to reduce the prevalence of ankle inversion sprains during basketball participation, footwear with incorporated
cushioned column structures are often promoted. However, the cushioned column has been shown to be ineffective
in reducing the loading rate. As much of the pressure upon landing is medial to the subtalar joint, a cushioned column
may further induce supination and an inversion moment. This potentially decreases the evertors’ mechanical advantage
in resisting inversion. A cushioned column also fails to atone for deviancy in the center of mass. Accordingly, further
research is encouraged in order to determine the optimal biomechanical shoe design for basketball participation.

As a serious supinator (bowlegged) and a runner I would endorse this comment fully. Very cushioned shoes have a tendency to cause me eversion issues.
