My Husband’s Favorite Socks
Size: Large, Color: (035) Steel / White / Black
The Under Armour Unisex Training Cotton No Show Socks have become my husband’s absolute favorite socks—and he’s pretty picky about socks. Comfortable Fit: They’re soft, comfortable, and fit well without being too tight. They stay in place all day with no slipping or bunching. Great for Everyday Wear: Perfect for workouts, walking, and everyday use. They provide just the right amount of cushioning without feeling bulky. Durable & Long-Lasting: These hold up really well through regular wear and washing. They keep their shape and don’t wear thin quickly. Reliable Under Armour Quality: You can tell they’re well made. Consistent quality that matches what you expect from Under Armour. Overall Impression: When someone has a favorite sock and keeps reaching for it, that says everything. These are comfortable, durable, and dependable.

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.
