I've seen them before but I can't remember where. I guess they're some Asian colour scheme that just didn't get released here. I can't imagine them making a new colour scheme for the old F50 when they're pushing the F50+ (and there's a red F50+ coming out).
They look like the cheaper version of the F50's because they dont seem to have a split sole on the bottom. Like the colourway though. appleCORR
they dont have a split sole because they are hard ground cleats but yes they are the cheaper version but both the "real" version and this version wont have split soles when they are hard grounds
They look like fake F50s, but are actually genuine Japanese F30s. Strangely enough they have a different F30 than everybody else... Still look crap though: the silver brace looks way too big and the spacing between the stitchlines is off. Amateur design!
