I took a close look at Nordic Walking by Malin Svensson. (2009)
Paperback and Kindle editions.
… Yet I’m still not convinced I’d benefit from hiking canes . I’m still suspicious Nordic Waltzing is a bit of a fad, especially in Europe.
… On the other hand, I don’t see the popularity of poles on the trail in decline. There are more & more each year.
Perhaps I need to get injured before really giving poles a fair try.
