Purpose built for the great outdoors, the Men’s KSO TREK is a more rugged version of our ever popular KSO.
The kangaroo leather upper and sock liner feels amazingly soft against the foot, yet is strong and tear resistant, with outstanding breathability. A 4mm EVA midsole offers plating protection from stone bruising, and a lightly cleated 4mm Vibram performance rubber outsole delivers improved traction on trails and over more rugged terrain. The TREK untilises Vibrams strong history of performance mountaineering footwear soles to create the Trek Sole unit offering increased traction and grip on mixed terrain. The Trek is the adventure racers dream shoe where less is definitely more.
Choosing the right size:
FiveFingers are fitted by actual foot length so when ordering please follow the sizing guide below to help achieve the best fit. It is quite normal to end up being quite a different size from your normal shoe.
How to measure your foot:
For best results in finding your size we recommend measuring both feet, heel to toe:
Standing with your heels against a flat wall
1.Slide ruler under each foot
2.Be sure to measure the end of the longest toe
3.Take the longer of the two measurements
If your foot length varies by more than 0.4cm, it will be difficult to get a precise fit for both feet.
If your second toe is more than 0.4cm longer than your big toe it will be difficult to get a precise fit

Special Note:
Again, it should be noted that not every foot fits well within FiveFingers, they are a very different approach to traditional footwear and "break" a lot of the old rules of what a shoe should be.
It's important to understand that the "break in" time for your foot to get used to the complete lack of padding and support can vary from person to person. Some people put them on and in a few days they feel great, for others the process can take a few weeks to be able to wear them distance running or all day casually. For a few the process can take months before they are truely comfortable for all day wear.
If you have known problems with your feet or are unsure if FiveFingers are for you please feel free to send us an e-mail and we can take you through the range and see how they may fit your feet and your lifestyle.
What if they don't fit me when I get them home?
Because of the toe fitting element of the Vibram Five Fingers they, on rare occasions don't fit, or are just the wrong size. We understand it is not always possible to try them on instore. For this reason if the pair you have don't fit or suit you please send us an e-mail and we can come up with the best way of fixing the problem from sending through a replacement size or offering a refund.
