Table 1.
The basic demographics of habitually unshod and shod runners.

2D foot print image of habitually shod (left) and unshod (right) runners.
Fig 2.
The dorsal view of foot surface data, length (length’), width (width’), minimal distance (distance’) and HA (hallux angle, HA’).
Three landmarks were drawn to connect line A-B (A’-B’) and line B-C (B’-C’), with A (A’) in medial calcaneous, B (B’) in the head of the first metatarsophalangeal joint and C (C’) in the hallux.

The length sample distribution of unshod feet and shod feet.
Table 3.
The width sample distribution of unshod feet and shod feet.
Table 4.
The one-way ANOVA of length and width of unshod and shod feet (mm).
Table 5.
The LSD ANOVA of hallux angle (deg) and distance between unshod and shod feet (mm).

A-The mean value of Hallux Angle (HA = 10.3±5.4 & HA’ = 3.42±3.5) (Fig 3-A), B-minimal Distance (D = 5.98±5.8 & D’ = 21.71±12.1) (Fig 3-B) and C-the correlation between the hallux angle value and the minimal distance with habitually shod feet (R2 = 0.057) and unshod feet (R2 = 0.182) (Fig 3-C).
