Help take the strain off your knees on steep descents with the Trail Pro Shock Trekking Poles from Black Diamond. The Control Shock Technology contained in these poles uses a system similar to your car's shock absorbers to help take the bumps out of the trail and lessen the strain on your joints. The aluminum alloy construction features a foam molded handle with a grip extension that allows you to choke up on steep ascents. The FlickLock Pro locking system allows you to make rapid, positive adjustments to the poles height to suit varying terrain. Carbide Tech Tips and low-profile trekking baskets are included to match trail conditions where you are hiking. An adjustable wrist strap lets you perform other tasks with your hands without dropping the poles.
