With Nordic Walking Speed Pacer Vario White 2012, I went for a test hike. They are very good clubs. They have sharp tapping and flexing well. Shoe has, but small flaws. All screws have fallen out after 30 km. With screws, sliding on the asphalt. Without screws beautifully kept. Clubs are very nice. Carbon structure would look good but much more. These are my impressions only an inspiration for you in the future and new models. Thank you from my heart for these Nordic walking sticks that help me be faster in the hills, during my long trips.
