Reduce impact of trekking or walking on knees, back, and hips2. Increase speed, balance, and security3. Get more traction and points of contact, crucial on muddy or steep terrains4. Great walking aid if recovering from injury or have balance issues5. Other uses: - Can deflect shrubbery or act as probe for puddles, quicksand, etc - Defense vs bears, other wildlife - Can double as tent polesAdditional advantages of Aluminum 7075While carbon fiber is lighter than aluminum, it does not perform very well under lateral pressure - common issues include snapping especially when it gets stuck on rocky terrain. Aluminum will not snap. It might bend under extreme pressure, but you can more likely bend it back and continue using it.Additional advantages of Lever LockAside from easy lengthening or shortening, poles with flip-locks can also be disassembled or reassembled easily. This is helpful if packing the trekking poles in a suitcase and shaving an inch or two off the assembled length is needed. With twist locks, it can be almost impossible to do this without breaking the poles.Satisfaction GuaranteeTrailBuddy stands behind the quality of the product.
