Using these Nordic walking poles is a breeze. First, adjust the pole length to your comfort using the Speed Lock+ locking system. It's easy to set it anywhere between 100cm and 130cm. When you hold the pole, the two - component cork grip gives you a great feel. The Trigger Shark 2.0 and the breathable mesh strap work together to keep the pole firmly in your hand, but if you need to, you can remove the strap in no time. As for maintenance, keep the poles clean. After using them in muddy or wet conditions, wipe them dry with a soft cloth. Store them in a dry place to prevent the aluminium from rusting. And always check the locking system before each use to make sure it's working properly.
