Ultimate Opaque Trouser Socks 3-Pack

I wore these under dress pants for a 10-hour workday and they never once slid down or bunched at the ankle. The four-way stretch really does snap back after washing, which I didn't expect from microfiber. Three pairs for this price feels like a steal.

These are the first trouser socks I've owned that don't sag by lunchtime. The four-way stretch really does snap back, and the microfiber feels breathable even under jeans. Wore them three days straight before I finally had to wash them.

I was skeptical about the four-way stretch claim, but these actually snap right back after a wash instead of bagging out at the knees. The microfiber is thin enough to wear under dress pants but still completely opaque.
