The role of ski poles is to obtainbetter support on the flat and in turns, to relieve muscles and joints by helping you stabilize effortlessly and to have better balance on your skis.
When initiating a turn, your"pole should be planted" to stabilize yourself and make you to tilt slightly to the outside of the ski.If the length is good , they will instinctively push you to swing on to your right side and therefore have enough weight on your downhill ski. In powder snow, thanks to larger baskets, freeriders can lean on them and turn without sinking into the snow.
Beginners are often comforted by the idea of having something they can lean on during the learning process and will help them get up after a fall..
In short, poles are useful for balance, rhythm and can help you turn faster or use them from braking, particularly in steep or difficult terrain.
