<p>To improve the ability for guiding skis in difficult snow conditions, the front end which is curved upwards, is provided with a keel shaped profile. The cross section through part shows a V-shaped profile on the underside of the ski. The keel profile can be made from plastic and can be fixed to the ski as an attachment when snow conditions warrant it. Instead of being V-shaped, the cross sectional profile of the attachment can be a convex curve.</p> |
