Classic 12-point Harfang Alpine crampons from Blue Ice. Thanks to the accessories you can use them as automatic or semi-automatic crampons. They can therefore be mounted on climbing or hiking boots. Just replace the front wire trapeze with a plastic basket. For use with ski-alpine boots, it is ideal to buy a front wire toe bail for ski boots: the BlueIce Standard Toe Bail. The connection between the front and heel is provided by a highly durable HTPE coated webbing instead of the traditional metal beam. This makes the crampons pack well.
