It is written that it "fits in size", but it is not so. I always wear size 8 1/2 shoes. After reading some reviews and some people recommending a half size up (they are also too small), I ordered a size 9 instead of the usual 8 1/2. Size 9 (or whatever they sent me as there is no size listed on the shoe) was WAY small! Even half an enlargement didn't help. I would recommend they have a US to China sizing conversion chart so people don't have to order and return because of an inaccurate description.
