Jeff B.wrote a review of Chaco Z/1 Classic Sandal - Men's on January 12, 2018
Familiarity: I returned this product before using it
Fit: Runs small
I've worn Chacos for ~20 years. Apparently they have recently changed their footbed and strap sizing. The 2 older pairs of Z1's I still have are both 11M which is the size I have always worn. Suddenly this version is a full size smaller than the older ones in length. So I tried 12M in this latest version and the 12 is the same length as my old 11 but significantly wider. Plus the straps are at least 2 inches longer which makes it impossible for me to tighten them down all the way as the buckle bottoms out against the ankle strap.
I'm done with Chaco.
