I was excited to try these shoes out. I've been experimenting with various minimalist footwear for a few months, from completely barefoot to huaraches to kinvaras. These looked cool and seemed to be a good compromise between minimalism and comfort. For a couple of runs they were great, offering some cushioning but still allowing for a midfoot strike. But once I started increasing my running time in them, and by that I mean only about 20 minutes, I started to notice a significant problem; They don't breathe whatsoever. I developed incredible blisters on my big toe and midfoot. My runs were miserable, my feet steaming in a wet sweat soaked oven. I ditched them and started running in my Vibram Five Fingers. Wow, what a difference! VFF's blow these things out of the water, and since they are about the same price it's really a no brainer. These looked cool and I wish I tried to like them, but Saucony just has a lot of tweaking to do before their minimalist shoes are competitive.
