Problem to solve
My problem is not liking to wear socks and still keeping my feet warm.
If I create an insole with heaters then, I would never have to wear socks and my feet would stay warm.
First, you cut the bottom of a sock that fits your size foot.
Then, cut the insole to the size of the bottom of the sock. Make sure it fits almost perfectly.
Next, sew the insole and sock together. The sock should be on top when sewed on. also leave a slot to put hot packs in..
Last of all, you put the hot packs in the pocket of the sock and you are all set.
What worked on the Sock-In-Shoe was that when putting in the heaters in the pocket they worked great. What did not work was constantly fixing the size of the insole to match the sock size almost perfectly, but it still worked.
