I absolutely love the style of these, but if the size is so hard to predict, what good are they? There is no consistency in sizing. Sometimes they are too big, sometimes too small. I always wear a 9 in any shoe. I purchased a 9 confident they would fit. They are huge on my feet. My toes didn't even go into the box- not even my big toe. Im returning them and am purchasing the H2s hoping I have better luck. I wouldnt mind going down a half or whole size if I felt like they would fit, but Im not going to go back and forth with Amazon returns forever hoping I find the perfect size. From what others say, most of the time these are close to true to size, but the shoes are not always the same as the rest. If I got one that was off, the 8.5 might be normal, and then its too small for me. Frustrating for them to all be so different. Hoping I have better luck with the H2, as Im going to Costa Rica next week, and I think Ill find them useful.
