I find it difficult to rate these sandals. It turns out that I had bought the wrong size. Not having had Birkenstocks before, I wasn't sure whether these are supposed to fit snugly or not. It turns out that they need to be quite snug. If they are too big (as mine are), your feet won't be in the right position and the footbed will cause friction and give you blisters instead of support. I am told by other people that these Birkenstock sandals are very comfortable and provide great support, but clearly it is important to make sure that you get the size right.
