so I would recommend sizing up one size.

The lowest (size 9) end of the range might be a little loose.

Nice socks, sizing description is just wrong, size up.

Size '4T-5T' must be the same as 'Small' because I ordered a Small thinking, 'Surely they wouldn't list T sizes, and then other more ambiguous toddler sizes under different labels

Size perfect

That was the perfect size

The sizes rotated up like children's shoes do

Wrong size.

These are nice socks but the sizing is very confusing

I ordered the wrong size.

The term big boys made me think it was for boys who are out of toddlers sizing, but this arrived with a sticker saying big boys 5 to 8, and then the actual package said size 2T to 3T, and the sizing is just right for my three-year-old daughter

Finally the sizing is just right.

The “medium” size socks are the right size (a tad on the big side but after washing drying will be perfect).

My son wears a size 4 and they first perfect.

They were DEFINITELY the wrong size for my intended kiddos, so now they will sit for the youngest until he grows into them...

I really hope this helps someone because i lucked out with the perfect size.

Sizing note - I ordered the large (3-10) - this size is perfect for my 7 and 9 year olds

Inaccurate sizing chart

Really though....how hard is it to provide an accurate sizing chart

The sizes are confusing

The size 9-2 ½ fit my 6 year old’s size 13 feet well
