Using these Cross Trail TA hiking poles is easy. First, adjust the length of the three - section poles according to your height and the terrain you'll be hiking on. When you hold the poles, place your hand through the wide mesh strap, which will keep the poles in place and reduce hand fatigue. Swing the poles naturally as you walk to get extra support and speed. As for maintenance, after each use, wipe the poles with a dry cloth to remove dirt and moisture. Avoid exposing the poles to extreme temperatures or harsh chemicals. Store them in a cool, dry place. And if you notice any damage, don't use the poles until they're repaired properly.
