I'm really excited about the new trail running shoes from Vibram. My current KSO Treks are in need of a replacement. When I first saw the BMX bike tire tread on the Spyridon's, I wasn't too enthused about them, but the more I read about them, the more I like it. According to Vibram, these should be in stores, or at least online, by February.
Leah at Birthday Shoes has written up a pretty thorough review of the new shoes if you are interested. Now to start tracking online retailers.
