Q: My skis slapping the track when I stride. How do I fix it? I do it the most during easy classic skiing, not so much in races.
Short answer: this is due to “late kick”; try thinking about driving the ski forward rather than kick backward.
A: Slapping-skis can often be an indication that a skier’s hips are too far back. The slapping sound you hear may be caused by the tail of the ski hitting the track too early because the “recovery” foot is landing behind the standing foot. Ideally, the recovery foot would be landing parallel/beside the stance foot, or even a few inches in front of the stance foot. If the hips are too far back, a skier is more likely to plant the foot too far back to gain balance, and in effect the tail will hit the track and make the clapping sound you are referring to.
As you ski, pay attention that your weight is in the front-portion of your foot. Before you start moving, gently transfer your weight from underfoot, to the front of your foot by leaning your body forward, making sure your hips come forward too. This is good basic positioning for classic striding. Also, watch that you are not “sitting-back” with your hips. A side-view of yourself taken on video will help give a visual indication of weather or not you are victim of “sitting back” with your pelvis and hips.
