I have a pair of Minnetonka moccasins that turn 6 or 7 this Christmas. My son used to give me a new pair of slippers each year until I got those. I've even cut grass with a push mower in them. Only once though because they kept flying off my feet and I had to keep stopping.
The soles look like new, the woven fabric liners are still holding up and they're comfy year round. In winter I will wear socks with them during the really cold weather. They're great around the house and to step outside to start the car on a cold morning. I've worn them to work accidently because I was in a hurry and forgot to change into work shoes. Half way there I realized it but had a spare pair of work shoes with me.
I've no idea the price or source but they are worth the coin in my view.
