So you have made the decision and bought some new crampons ready for the winter, all you need to do know is fit them to your boots. This step by step guide is designed to make that process as easy as possible and should be read in conjunction with the manufactureres own instructions, if provided. Types of crampon will vary slightly in the way they attach to the boot but the principles remain the same.

Line the boot up with the crampon to get an idea of whether it is too big or too small to start with
Adjust the length of the crampon on the centre bar. The crampon wants to fit snugly on the boot without the heel overhanging at the back and with as much of the front points protruding from the front of the boot as possible.
Fit the boot into the toe bale and then adjust the heel bale so that when you click it into place you get a nice firm click. The bale sits in the plastic groove on the back of the boot.
Once the crampon is the correct length and the bales have been adjusted the crampon should sit on the boot when it is lifted in the air. (Without the straps being done up)
Do up the straps by passing them across the front of the boot and through the tow bale and then through the two metal rings and back through one. Some crampons are different to the one shown in the photo and you should follow the instructions that come with the crampon.
You now need to trim off the excess strap or it will become a trip hazard. Don't trim too much off or you won't be able to do them back up. Its best to trim a little at a time and check that you still have enough strap for doing the crampon up. Remember that you will normally be wearing gloves.
To finish tuck the remaining strap out of the way.
You will need to melt the cut off end of the strap to stop it fraying, use a match or lighter.
