I love Ahnu shoes!!  However, having to choose a whole size on some styles is a tough judgement call. With a toe thong, it throws the arch fit off a bit as well as putting my heel right at the edge whereas one without a toe thong is a perfect fit. Their sandals are lightweight but have superior arch support. Its almost like going barefoot when you were 7 and didn't need arch support and padding.  I hope that Ahnu will look at providing half sizes and wide widths for an even bigger buyer opportunity.
