The lacing system consists of two continuous laces that loop around support points in the upper part and around the heel of the shoe. The lock is a 3D printed double-loop cinch that keep the laces in place. Along the heel is another lace-lock to keep the network from sliding. The textured skin beneath the exposed structural lacing is an abrasive-resistant poly-urethane fused to a Lycra base. The upper part was lasted and baked at 300 degrees to hold its form in place.
