Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape. My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days. That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.

Fits well! XL is Real!
Color: (239) Elite Beige / Elite Beige / Halo Gray, Size: X-Large
As far as I know, these are the only XL no show tan socks on Amazon that actually fit a size 14 foot. I've tried a few other that don't fit after wearing them once. This is a regular feeling sock and not the thin hose type like other XL.
