Out of all the socks we've tried, these are the winners.  Good fit, true to size.  Just keep in mind that they are a little on the thick end, and if that's what you are looking for, you will like them.  If the child's shoe is just fitting them, then these socks won't work.  If the shoes are a good size with wiggle room for the toes, then I find that these socks are what work for us.  They last long and he's outgrown the socks before any holes formed.  Never a hole yet.  Keep in mind though, that he also doesn't wear socks around the house on the rugs, therefore, there isn't much wear and tear for the socks to withhold in that respect.
