The three silhouettes in this pack are armored with a SUPRATUF® material that uses an advanced technology to create a mold that has the effect of woven fiberglass. This exceptional material has been used only once before by SUPRA (on the Society Black Widow—an extremely limited edition, 413 release). You can now experience this new SUPRA TUF treatment yourself in the Society, Society Mid, and Stacks that make up the Fiberglass Pack. All three come in battleship grey, with black accents, and white soles. The Fiberglass Pack is now available at SUPRA retailers worldwide, and http://www.suprafootwear.us.
