I love vff's but my main problem is that I get stone bruising when running on rocky stuff, which was the reason that I got them as I was getting stone bruising when barefoot running on rocky stuff! The treks look good, but I think I'll wait and see what inov 8 come out with next year. I would be happy with a shoe similar to say Rocklite but with a completely flat sole and perhaps just one level of cushioning - my feet are feeling tender from all this bruising.
