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.
