Im gettin weary bout my sons shoes on him?

It's kind of the way it is, kids hit growth spurts and they GROW, would you like him to not grow? My sons seem to grow in their feet, then their limbs and then their torsos and then they fill out, he's just getting ready to gain some height. If it were me I'd believe him if he said they don't bother him, it will bother him when his toes are cutting through the tops or he's wincing in pain when he runs - but until then let him be.
