Before you begin these steps, it is easy to make a tool like this.
Step 1 Turn the boot inside out like this.
Step 2 Place the boot into the hot water.
In the hot water, the rubber become more flexibeler.
So that it easier to slide over the tip.
Step 3 Remove the rubber from the hot water.
But before you take cover over the point you make sure that he is well greased.
And bring the boot in 1 time over the point
Step 4 And bring the boot back in its original condition
I hope that these tips help
