Aquathlons and Vibram Five Fingers (KSO Treks and Sprints)

The Treks are doing great, they were the first VFF I bought and are still my favorite Vibram model. I bought them when they first came out in September and took them out of the box for a 14 mile run. This was after a few weeks of barefoot running which in retrospect was way too little foot strengthening for running such a distance, but luckily I have done just fine. I also have bought the Classics and the KSOs which I also think are great, but the Treks Roo leather wrap around my feet more tightly and comfortably, some refer to this as a more luxurious feeling. The sole has a great grip, even in asphalt, and being a little thicker than the others I think it is more forgiving on newbie running mistakes. Perhaps this has to do with no injuries and many, many miles since I got them back in September.

My only minor complaint is that on very long runs (over 15 miles) on hot and humid conditions the leather inner sole feels a bit slippery. I actually did not swim on them in the aquathlon as they were considered an artificial propulsion device under the rule book … not sure how they would have helped me swimming but the rules say:

Any swimmer wearing any artificial propulsion device, including but not limited to fins, gloves, paddles, or floating devices of any kind shall be disqualified.
