They are very cute and I believe are authentic, but they run HUGE. I'm a solid size 8.5 in women's shoes. I ordered these in men's size 6, and they are the equivalent of at least a women's 9, and possibly even 9.5. I have three other pairs purchased from the Converse retail store and they are not this big. See my photos. Unsure what to do, as my size is gone and the color on these is so lovely. If you're a woman and ordering in men's size, I suggest going down three whole sizes (at the least, 2.5).
