Is never a good solution to do some ice part with running shoes. Crampons are or to soft or adapt for alpinism shoes. Soft crampons are adaptable to running shoes but they can not break the hard ice. Automatic crampons are to heavy and painful when we put on running shoes, so here my solution how to have a rigid crampon, light and that keeps on running shoes:
So here how to have a rigid crampon, light and that keeps on running shoes:
– We take a steel front and a aluminum back and bar:
the toe of the shoe enters on the bar. Is important to put the strips to keep the crampon on place when we flex of the shoe, if not, the front part can fall on steep ice
The back can be on a automatic crampon or on a manual crampon, as comfortable as for the shoe, the automatic clips well on the end of the EVA part of the sole.
And to be more comfortable on the front (yes, the bar directly to the shoe makes a lot of pain on the toes after some hours) we can put a thin (2-3mm) part of neoprene or eva (inner soles of a shoe)
Now time to climb!!!
