Values are expressed as means ± standard deviation. Pg: comparisons between the LSS group and the control group using independent sample t-test; Ps: comparisons between the 2 tests in the LSS group and control group using paired t-test. CA%: contact area % (contact area of the 10 foot zones normalized to the whole contact area of the foot). 1st: first test. 2nd: second test. T1: hallux. T2–5: toes 2–5. M1: first metatarsal. M2: second metatarsal. M3: third metatarsal. M4: fourth metatarsal. M5: fifth metatarsal. MF: midfoot. LH: lateral heel. MH: medial heel. ∗P < 0.05.
