These poles have the intelligent overall design of excellence which is what makes them light, thin, stable but still extremely comfortable. This model is made from high-tensile strength aluminum along with LEKI's Dynamic Suspension System antishock system to reduce peak pole impacts by as much as 40% to protect muscles, joints and ligaments. Featuring an Aergon COR-TEC grip and the innovative next generation SpeedLock Plus locking system, you will have a hiking experience that's simply unparalleled, whether it's a hike up Crowder's Mountain or a trip to the Grand Canyon.
