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.

Absolutely Essential for Any Athlete or Gym-Goer!
Size: Large, Color: (035) Steel / White / Black
I recently purchased the Under Armour Unisex-Adult Training Cotton No Show Socks 6 Pack, and I must say, they've become an indispensable part of my workout gear. Here's why these socks are a game-changer: Comfort Above All: These socks are incredibly comfortable. Made from a blend of cotton and synthetic fibers, they provide just the right amount of cushioning without feeling bulky. Whether I'm running, lifting weights, or doing yoga, my feet feel supported yet free. No Show, All Go: True to their name, these socks stay perfectly in place without slipping down into my shoes. This is crucial for maintaining a professional look at the gym or during sports activities. No more embarrassing sock peeks or having to constantly adjust them. Durability: For the price, these socks hold up remarkably well. I've washed them multiple times, and they haven't lost their shape or elasticity. They've survived the rigors of both my workouts and laundry day. Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions. Pack Value: Getting six pairs in one go is fantastic. It means I always have a fresh pair ready, which is perfect for someone like me who works out frequently. Fit for All: These socks fit true to size and are designed to be unisex, making them a versatile choice for anyone looking to upgrade their sock game. If you're in the market for socks that combine comfort, performance, and style, look no further. Under Armour has nailed it with these no-show socks. They've quickly become a staple in my wardrobe, and I find myself reaching for them over any other sock I own. Highly recommended for anyone serious about their fitness routine or just wanting reliable, high-quality socks. 5 out of 5 stars - These socks are a must-have!
