The point is mostly to contain the inevitable griping to some degree.
If there’s a c/ where complaining about reddit is the default, then it’s easier to channel such things to that c/ rather than dealing with it constantly in other communities. Can’t say how effective it actually is, but that would be the point imo













Nah, as long as it isn’t significantly different, all that matters is that it isn’t going to irritate and rub.
Mind you, the more of a difference there is, the less comfortable it’s going to be in shoes, no matter what material it is.
You might run into the patch job wearing the surrounding fabric out faster if there’s a decent difference as well, but it isn’t like something that thin is going to last very long once a hole appears anyway.
