I wear a women's size 7 or 7-1/2 depending on the company. I haven't worn Chaco's before. Can you tell me how their sizing runs in comparison to Olukai or Teva?
I can only speak to the Men's sandals, but all my Chacos run true to size, that is, consistent with the size I wear in my running shoes and other sandals.
I would say to go with a 7-1/2 with flip flops its always better to go up than be too small.
