I was gonna deal with them too, them I got in touch with the cats that run it and decided not to. What makes me think they sell GM's is the fact that they have tons of shoes in several different sizes that are tough to get a hold of, plus they don't show pics of the parts of the shoes that would be identifiers of fakes. They also say there is a "7 day handling period before shipping due to high demand". I have encountered peeps that do the same thing, and they're basically middle men for someone who gets GM's and passes them off as authentic. I had looked at the SJ's they have for sale, and the soles look icy as hell from the side, and they don't show the "23" tab in back or the bottom of the soles.
IMO I'd say look somewhere else. They want $300-$400 for some suspect 11's you can get from somewhere like sole supremacy or rif.la that will be 100% authentic
