Pure class, top notch materials and craftsmanship. I only wear barefoot shoes (converted to Xeros and Vivobarefoots for ALL SHOES about 4 years ago) so initially I didn't know what to expect with the sole and if it would be as flexible as I wanted, sure enough it breaks in beautifully! I bought these for my wedding and my feet feel free and happy. These are the only option in the market if you want barefoot movement + high quality leather + formal/beautiful construction. A note on the heel - yes, it's stiff but it provides some give as the shoes break in. Movement wise the heel is not an issue, but it does provide slight elevation that's little different than my other barefoot shoes but I don't care about this, these feel great on my feet!
