The Tanjun runs a half size small.  After dialing in the correct size, their comfort is amazing.  The outer sole is very light yet provides good support.  The thin mesh upper wraps around your foot and after a week or so will conform precisely to the shape of your foot.

The thin mesh us well ventilated for summer weather but looks delicate.  I am curious whether the upper will still look good in six months.

The Tanjun is a good choice for people who are on their feet ten or twelve hours a day.
