Amazon EssentialsBoys' Cotton Crew Sports Socks, 10 Pairs

Amazon. wacky idea here: make it clear what size all your kids socks are. for the love of god, how hard is that? why is that not super obvious?

Pulling my hair out....its socks, why make it tough? size chart shows "2-3" or "4-5" but the socks come in s, m, and l?

What size is ideal for 8 year old who wears size 13 .5 in shoes?? Also do these shrink ?

Are the Size 4-5t correctly sized? My son wears size 10C shoe
