I wear a women’s size 9.5 and I got a size Medium. They fit perfect, they aren’t super heavy, but have cushion where needed. Perfect for my steel toe boots

Quality and durable socks
Size: Large, Color: White (6-pairs), Number of Items: 6
Great quality socks. This pack was a lot taller on the cuff and bigger than previous batches I have had. Not sure what the change was, but giving it 4 instead of 5 because I preferred the smaller shorter ones they previously made. But these are great quality socks, and last a long time.

A Game-Changer for Comfort
Size: Medium, Color: Black, Number of Items: 6
I recently upgraded my workout gear with the Under Armour Training Cotton Quarter Socks, and I must say, these socks have revolutionized my exercise experience. Comfortable, durable, and stylish, they truly stand out in the crowded world of athletic socks.
First and foremost, the comfort level of these socks is unparalleled. The blend of cotton and synthetic materials provides a soft and plush feel against my feet, making every step a pleasure. The quarter length strikes the perfect balance, offering ample coverage without being too restrictive or too short. It's like walking on clouds, even during the most intense workouts.
One of the standout features is the moisture-wicking technology. I've worn these socks during high-intensity cardio sessions, and they have consistently kept my feet dry and comfortable. The breathability is remarkable, preventing that uncomfortable feeling of sweaty feet that often accompanies strenuous workouts. No more distractions – just focus on pushing through your fitness routine.
Durability is another strong suit of these socks. After numerous washes, they maintain their shape and elasticity, showing no signs of wear and tear. The reinforced heel and toe areas provide extra support, ensuring longevity and preventing the dreaded sock holes that often plague other brands.
The sleek design of the Under Armour Training Cotton Quarter Socks adds a touch of style to my workout attire. The subtle logo and choice of colors make them versatile enough to pair with any athletic shoes. Whether you're hitting the gym, going for a run, or simply running errands, these socks seamlessly blend fashion with function.
In terms of sizing, I found that they fit true to size. The elastic band around the arch provides a snug yet comfortable fit, ensuring that the socks stay in place throughout any activity.
While the price point may be slightly higher than some other options on the market, the quality and performance of the Under Armour Training Cotton Quarter Socks more than justify the investment. When it comes to comfort, durability, and style, these socks have become an indispensable part of my workout wardrobe.
