I agree with the previous reviewer:  these are quite thick for "crew" socks.  They are as thick as sport socks.  Nevertheless, they are true to size and good quality.  Fast shipping.  Great colors.  Great under jeans.

Update:  A year later, these socks are still going strong!  No holes or thin patches.  Still stay up and fit well!  They've been washed A LOT over the past year
