Vibram FiveFingers are designed to simulate walking or
running barefoot, but with the protection of a shoe.
The KSO Trek is a more rugged version of the original KSO, with Kangaroo leather uppers, a 4mm EVA midsole to protect from stone bruising, and a lightly cleated 4mm rubber outsole for improved traction.
The separated toe
compartments provide the flexibility and individual muscle movements of
a bare foot, while the performance rubber sole ensures protection and
solid grip.
The KSO Trek leather uppers are soft against the foot, but strong and very breathable. Like other FiveFingers models, these shoes are machine washable!

Sizing:
Sizing is determined by foot length. Vibram recommends standing with
your heels against a flat wall, sliding a ruler under each foot,
measuring the longest toe, and taking the longer of the two
measurements. If your foot
length varies by more than 1/6 inch, or if your second toe is more than
1/6 inch longer than your big toe, it may be difficult to achieve a
satisfactory fit.
Foot length in inches (+ or - 1/8") to KSO sizes:
9 3/4" = 38
10" = 39
10 1/4" = 40
10 1/2" = 41
10 3/4" = 42
11" = 43
11 1/4" = 44
11 1/2" = 45
11 3/4" = 46
12" = 47
12 1/4" = 48
