These sandals were comfy out of the box - no breaking in period.  I have a wide foot, so ordered the wide.  They are plenty wide- could have almost gotten the regular width.  But I needed to use them for a trip and they did not disappoint as I walked over 11,000 steps (5+ miles) on the first day I wore them.  I won't be wearing them with my pretty dresses/skirts, but for those treks outdoors and in the city, they are perfect.
