Tiffany (aka Hutch) and her husband did a great He Said She Said review of the Phase and Form.
"Almost feels barefoot. Phase is wider and flatter through the arch than my Merrell Barefoot shoes and have a less constricted, more sock-like feel. Phase also has a slightly thicker toe box which is appreciated for protection. The heal of the shoe comes above some of my low-cut socks. These are my favorite shoes to wear around the house because of how light and comfortable they are."
