These socks are delightful.  The only fault we have found is with the pairs that have an "extra" added to the top.  This additional top makes the socks extremely tight around the leg causing concern about circulation.  Since I bought these for my grandson, my daughter chose to cut off the additional top section.  They fit much better and it doesn't seem to have a negative effect on the fit at all. Plump little baby legs don't need the extra tightness.
