I bought a pair of Leki Super Makalu. They had rubber grips, wrist straps, and anti-shock. I didn't like the anti-shock. I tried it over several hikes, but couldn't get used to it. Wrist straps are great for general hiking. I think they make a difference when used properly. I didn't use them for scrambling over rock falls. Afraid of falling and breaking my wrist. The rubber grips gave me blisters one time while hiking long distance in the rain. Changed my grip after that and no more problems. They really helped me out on a backpacking trip, from a knee problem. The light weight and multiple sections make them easy to carry (or pack in your checked luggage). Spend a little less and avoid the anti-shock. Mountainsmith makes an economical lightweight aluminum pole without anti-shock.

Finding info on correct height adjustment, how to tell right from left on the Leki, etc can be tricky.

Foam grips are comfortable when new, but I'm not sure how long they will last. The rubber grips (or cork) will give you the most life.
