Bruh, full retail is $75...
I been looking for a pair of Calypsos for 6-8 months before these dropped. When I found pairs on ebay, the cheapest I found was $125, some as high as $180, with most around the $140-$150 mark.
As far as the differences between the OG, 2013, and newest release, the color just doesn't matter (to me). We all know that the same shoe made in different years by Nike is going to have some differences. Sucks, but that's the way it is.
The only unforgivable thing with these new jawns is the insole. The foam insole earlier roshes came with is part of what makes the shoe. I'm in process of buying cheap older pairs specifically for the insoles, just so i'll have enough to rotate between the pairs I wear on a regular basis.
IF someone with that good entrepreneurial spirit could find what material it was, and recreate them, I'd easily pay $20 and buy multiple sets.
