I purchased the low cut no show socks last year and they were amazing.  Stayed on my feet all day long with maybe one or two adjustments.  They wash well too.  I wash them with my delicates then hang them dry.  I came back to order more as I wear them everyday and decided to order these mid cut socks to wear with my loafers and canvas shoes.  They are great!  Not too thick so they are perfect for the summer.  Stayed on my size 5 feet also.  I must talk about the superior customer service too.  I ordered 2 grey and 2 nude but got all black.  It didn't bother me too much as they were no show but I emailed Elizabeth anyway to let her know.  Elizabeth is the customer rep who checks up on you after your purchase to make sure you are completely satisfied.  Guess what...she told me to keep the black socks and sent me a new pack of the correct colors!  Thank you Elizabeth!  Best customer service I have experienced on Amazon.  And great quality products.  Highly recommend.
