Perks
Leki developed an adjustable anti-shock system for the Summit poles that allow the user to set the spring to medium flex or completely off for steep uphill jaunts. They also feature carbide tips that flex up to 30 degrees to avoid damage to the pole shaft and wear and tear to the carbide tip.
Sacrifices
Due to their durable construction and anti-shock system, the Summit trekking poles are heavier than similar competitors' models, including REI and Black Diamond. Also, Leki places the anti-shock springs inside of the shaft making them hard to get to if repairs are needed or oil is needed to be applied to the spring for stiffness relief or to quiet squeaking sounds.
Bottom Line
The Leki Summit trekking poles are loaded with beneficial features and offered for a lower price than competitors' poles. They are recommended for any hiker or backpacker.
