I'm really confused by the "perfect size" ratings. I normally wear a size 12/12.5 and was surprised how insanley tight these are; I would need at least a 13 probably. Also, I'm confused about the 2-tone blue shown in the pics, I loved that, but what i received was just the darker blue on both shoes. i'm 3-stripes-4-life all day every day, but this was disappointing, and hopefully just some weird fluke. I will be returning these.
