I read the reviews first because I had no idea what size to buy. My son is 6 years old and wears a US size 12. I ordered a medium size and they fit perfectly! I washed them and tried them on him and am happy with the purchase. They are of good thickness (not too thick, not too thin) and feel comfortable.
