From: Pattern of outsole shoe heel wear in infantry recruits
Shoe heel abrasion. (a) This right shoe is worn from 7 o’ clock to 6 o’ clock (almost all the way round). The maximum abrasion is at 1:30 (laterally, as this is a right shoe). The massive wear can be noted by the disappearance of most of the grooves, also more laterally. (b) This causes the shoe to stand slightly slanted to the right (inversion).
