I wear a size 12 in both roshe and flyknits. I can wear them with or with out socks fine as the laces allow a lot of room depending on how tight you tie them as the material isn't structured like a leather or hyperfuse shoe. I took a comparison photo between the multicolor flyknit racer and the flyknit lunar 1+, I will post them later today. The shoes are the same size but the Lunar look bigger then the racers, a lot bigger. They also feel heavier then the 1.x oz difference the shoes are listed being. The colors seem more like dots then lines and is over all much darker then the racers. The lunars do come with a pearlescent / glittery finish on the midsole. Look and feel I prefer the racers, the Lunars are going back, I'll cop on disco if anything.
