You can actually buy new sheepskin inner soles. I've seen them at that sheepskin shop on the side of the highway in the blue mountains. Which gave me an idea. I can be frugal, and cut up some old ugboots to make my own sets of inner soles for my newer ugboots!
I finally got to do that this week. I've been keeping my old ugboots for years, waiting for the moment of need. Their time has come!
I made a template by drawing around new ugboot sole. I then drew a line inside it a bit smaller so that it would fit inside. (I just fished a cereal box out of the recycling for my template material.)
Then I cut the sole off my old ugboot. Sheepskin is a bit hard to cut, I suggest doing little snips through just the skin, not through the wool as well. The wool pulls apart once you've snipped through the skin.
Drew around my template on one side of the boot, using a texta.
Then I flipped the template over and drew around it on the other side of the boot. You have to flip the template over so that you get a left and a right foot.
Here they are! They are a perfect fit and my feet are happy.
Not much left over from the old boot. I'll cut a spare pair from the other boot and put them away somewhere for when I need to replace again. If you have a family of ugboot wearers, you could do this all the time and share out new inner soles whenever a pair gets holes in it.
