Date Dec. 19, 1985.A device for attaching a boot (5) to a ski (11), especially a cross-country racing or cross-country touring ski, comprising a locking assembly (12,12b,14) on the ski (11), which co-operates with portions of the user's footwear for the attachment thereof to the ski. For the purpose of achieving a lockable connection between the boot and the ski which secures a good side guidance as well as free and unobstructed lifting movement upwardly to a correct, limited degree, at the same time permitting an orthopedicly correct boot, such as an ordinary hiking boot to be used, the present invention discloses a novel locking assembly (12a, 12b, 14) which is provided on the ski, when can co-operate with attachment portions (6, 7) which are defined in the footwear sole surface (1) in the area of the toe portion (2') of the foot. By this form of attachment device may be the boot locked to the ski in the area of the axis of the pivoting movement of the foot, allowing the foot to swing about a fixed axis without play, which allows for good control of the skis, even with a completely swung-up foot. Attachment portions (51a,51c; 51b, resp.) having individual locking mechanisms (552,55c; 55b, resp.) permitting displacement of the attachment point of the sole relative to the binding (54) are also disclosed.
