Shuffling around the house in my stocking feet working at home, has left me with pairs of socks; although originally thick wool, ribbed, elastic crew-length; with the heels thread-bare or worn through.
They're beyond mending within my ability in my opinion. In the past, when this happened, I tossed them out. I don't enjoy wearing socks without heels. I have a few pairs that I've kept, thinking that there might be some other way.
I would like to find a hack to extend the useful life of the worn pairs of socks with as minimal effort as possible. The longer the hack works, the better — from simple conservation of resources if nothing better.
I thought if anyone could come up with an out-of-the-shoebox solution, it would be a lifehacker.
Edit: BTW, my sewing skills are great. I've made my own tunics, ditty bags and camping gear—but I'm LAZY and easily distracted. :) I have 3 pairs of different-style 'slippers' but enjoy walking on glass-smooth floors sans footwear. Yes, some rooms have carpet or rugs.
