John W.wrote a review of Black Diamond Spire Elliptic Trekking Pole on January 8, 2011
I am very happy with the Black Diamond Spire Elliptic Trekking Pole.
The elliptical shape of these poles gives them strength when hacking up a steep trail on snowshoes.
Few other poles on the market are as light and sturdy.
Cheaper poles may a few seasons (or a few hikes) and then fail you. Black Diamonds are a durable good meant to last for years.
If you snowshoe, these are worth the investment.
