Good for one wear
These definitely look like trouser socks, and there is some compression.  These are certainly very thin, which is good for summer and for shoes that need a thin sock (like heels).  I bought these originally because I am 8 months pregnant and have some issues with swelling in my feet and ankles.  I  would have rated them higher, but wore them once, hand-washed them like the package directs, and then put them on a second time, only to discover a run from the ankle to the top of the sock.  Rather disappointed.  I will continue to wear them until they fall apart, because of how bad my swelling gets, but would definitely recommend anyone looking for compression socks to get a heavier weight material.
