I bought these socks for running.  I had been wearing out my old running socks and needed new ones, but didn't want to spend a lot of money.  These have been great for short to medium length runs (I have a pair of nicer socks I use for long runs of 10+ miles).  They do show a little bit over your shoe, and normally I like no-show socks, but I'm ok with it since it means they stay up!  (Really annoying when socks fall into your shoe while running).  To give a little background, I run about 30-45 miles a week, and have been very happy with these socks on general training runs.

Also, the "5-9" size fit perfectly, and I wear a women's size 8.

Very good running or walking socks for the price.
