Tyler Jackson wrote a review of Black Diamond Spire Elliptic Trekking Pole on March 10, 2012
I'm gearing up for a trip with some serious hiking on it, and having suffered from JRA in my knees and ankles since 13, wanted something to reduce the wear and tear on my knees. I've taken these out for a few test runs, and they are an absolute lifesaver. Anyone with weak knees or ankles, or anyone wanting some extra stability on the trails should have some trekking poles. These poles performed beyond my expectations.
