I have a set of Leki poles. I often use them 2hen hiking or even walking in town. I have rubber covers for the carbide tip. They stabilize and protect ankles from turning. They also help to excerise your arms and back.

I bought my girl friend a pair from Walmart. I was not sure how much she would use them. We both keep them in our vehicle to use when we go out for a hike.

As others have stated, they help both uphill and down.
