Had no idea they called it Nordic walking, saw people using trekking poles at Yellowstone so I bought a pair.
It really makes walking a lot better, especially when you are on uneven ground. And you can go faster too.
If you don’t have a set you might think about getting some for your next trip to the mountains.
I started using them about 8 years ago to extend my hiking life. Really helps the knees, especially on down hills.
