Quality Under Armour socks

Size: Large, Color: (100) White / White / Black

Nice medium thick sock that is breathable but cushioned. It stays put in the show and doesn’t fall down. Fit is true to size, no show/minimal show

Excellent athletic socks

Size: Large, Color: (100) White / White / Black

Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.
