I have the Crampons and a new rubber sole on the boots. My next step is to line up the crampon parts and drill through the sole of the boots to bolt the crampons on to the bottom. I am headed to the hardware store tonight to get some T-nuts and bolts to use and install. I am also going to add some silicone calk to the bolt holes to keep it water tight. I hope to update this and finish the project this weekend as I will be on the road for the next few weeks working.
