From the “mind” of illustrator Todd Bratrud, the Brain Wreck Edition of Nike Dunk SB High’s incomparable Grey Matter quilted lining made it a highly sought after offering this holiday season.  Now comes another, an un-release sample from Nike SB that precedes the final versions.  The differences are negligible if not unnoticeable, with one exception – the inner lining.  Instead of the elaborate quilted liner in grey, the sample edition feature imprinted brain grooves in vivid pink with a matching sock liner.  This unique offering comes only in sample size of 9 and currently available via: MentalKicks.com
