Following tomorrow’s release of the Concepts-designed “SEAL” 999, New Balance has prepped additional colorways of the silhouette for a release next year.

Donning shades of grey throughout the premium suede upper, both pairs sport contrasting accents on the ripstop nylon heel panel, upper eyelets, tongue and heel branding.

Blue and red versions are both slated for a Spring 2012 release.
