I have only owned these for a few days but am very impressed. They are so comfortable and light that I don't notice they are there. I expected the straps to feel like they are digging into my feet when running, but they do not at all. I have only done a few short 400m runs so far, and will update my review after a month or two of regular use.

I like these MUCH better than my Vibrams. My feet feel more free and natural, plus no nasty Vibram foot odors with these because they are open and breathe.

I ordered the Z-Trail first and they were too narrow, but the Z-Trek fits my wider feet perfectly. I usually wear size 10.5 shoe and wear an 11 Z-Trek.
