So I just threw out my first pair of vibrams, which were the old TrekSport model. They did a good job, but finally started to fall apart. I still have a pair of KSOs with the natural sole, which work ok for stuff around town, however, I need something that I can start backpacking/hiking in, and the KSO won't cut it.

I was thinking about getting another solid pair of TrekSports, but they're pretty bland, and I was looking at the new Spyridons, which claim to have incredibly grippy soles and a new sole technology that protects better from bumps and jabs, though the are .5 mm thinner than the TrekSports.

Has anyone tried the Spyridons? Is at a worthwhile upgrade? Will they protect/perform better than the TrekSports?

Thanks in advance!
