Titan is lightweight, weighing only 3 1/2 pounds a pair.  Don't let the weight fool you, the Titan is a tough boot.  It features a solid nylon midsole for climbing support, a durable rubber rand, and a lace to toe design so you can control the support of the boot upper when lacing.  A once piece waterproof membrane, along with a cushion contour insole, adds to the comfort of the boot.
