I like thick toddler socks because they make shoes last "longer"... that is, a slightly larger-sized shoe will start earlier.  And we certainly go through a lot!  Soft and comfortable, wash and dry nicely, a basic sock in neutral color.  Elasticity so far seems decent, so I'll see if it stands up to time.  Stretch is definitely a plus, so these look like they will last.  True-to-size.
