All parts are replaceable, with molded-in frame components that make part replacement easy, fast, and economical. A variety of individual parts and kit options are available to suit your needs, so you can upgrade what you want, when you want. Adjustable ribbed elastic straps are pre-angled for two strap placement options. Robust ribbing allows the Smartlock Plus buckle to securely grip the strap and lock into place with just a pull—no slipping or overtightening. The Smartlock Plus quick-release buckle is an ergonomic, large-format design that’s gentle on fingers and locks in your strap length for all-day comfort. Tucked-in liners provide a snug, stay-in-place fit using breathable, wrinkle-free wick-tech material for added comfort. Cushion inserts come in two thickness options (5/8″ or 1″) and are made from resilient, replaceable cellular urethane to absorb shock from kneeling. This listing features the 1″ cushion option. The rubber boot is constructed from tough, non-marking 3-ply white polynitrile, featuring a 3/16” thick non-skid design suitable for all surfaces. Radius ribbing around the frame perimeter offers maximum flexibility during extreme kneeling, molded from tear-resistant plastic resin. The live hinge allows a “fit like a glove” feel with a 10.5° maximum flexible joint. The contoured knee pocket and flat bottom design help stabilize the knee joint, reducing joint stress and minimizing knee burn.
