<p>The object of the invention is a shoe and a method to attach it to a ski and to a skate. In the outsole of the shoe there is a longitudinal groove (1), in which four iron pins (2) have been set transversely across the longitudinal axis of the sole. One of the pins is located close to the front end of the sole, one close to the heel end, and the other two between them. A guard piece is attached to these pins to protect them from damage during walking. The guard piece can be fitted with spikes to prevent slipping. Also, a skate blade or roller wheels can be attached to the pins instead of the guard piece.</p> |
