its not that NikeSB is putting out garbage, the truth is that the division became very popular and in order to keep up with high demand of the shoes and designs nike had to start putting out more shoes/color ways. as it grew with popularity (like jordan and other divisions of nike do) they began to try and branch out and make themselves appeal to new fans of the sneaker game and those who never wore SBs before.
so now Nike SB is a monster, its huge everyone knows about SBs so they put out 4-6 shoes a month and we boo them, but by the end of every year there is going to be a small hand full (4-5) of releases that will have had everyone going crazy, this year we already seen the Skunks with huge success and the American dunks seem to have had some high popularity, there seems to be a trend maybe once a season a pair will come out and really shake the game up.
dont worry guys NSB is going to release some heat its just not as consecutive as it used to be, were just going to have to accept that.
