A sock with real support and thickness!
Size: Large, Color: (001) Black / Black / Pitch Gray
I’m pretty happy with these. It seems like sock manufacturing changed 10-15 years ago, and it’s become hard to find pairs that are actually thick and durable. I bought these for an event where I knew I’d be on my feet all day, and they did not disappoint.
They provided excellent support throughout the day, even while wearing shoes that typically make my feet ache after just a couple of hours. Glad to finally find a pair that feels well-made.
