The thread on the shoe was very rough in one spot. Had to return them because they rubbed a blister almost immediately. Some Sanuk sandals are made better than others. After having ordered several, both men's and women's styles, I determined that the sandals that were made in China were better than those made in Vietnam. Different colors in the same listing can be manufactured in different countries. i did not see any way to determine the country of origin on the Amazon website. Some Sanuks are absolutely wonderful, while others have manufacturing defects that negatively impact quality and comfort.
