My favorite low socks ever
Fit Type: Classic Fit, Color: Gray Assorted, Size: Large
Under armour adult essential Lite no-show socks are 96% polyester and 4% spandex footwear of imported origin. The polyester content of the socks enables them to hold their shape in a better manner along with having a non-absorbent nature. Additionally, it enables the socks to retain the colour in a better manner. Spandex improves their fit along with helping them last for longer time.
The flat fit construction of UA Men's Essential Lite is so designed to conform to foot for superior touch and feel. The material wicks engineered within the fabric dry sweat quickly and keep the feet fresh. The embedded arch support further keeps you going by reducing foot fatigue. The set comes with 6 pairs of socks with pull on closure for the perfect fit.
Ultrathin lightweight construction of the socks adds to user comfort by allowing users to conduct physical activity and work out while wearing it. Elastic strength of the socks prevents them from slipping down irrespective of the shoes they are worn with.
The socks come in 8-12 men shoe size and 9-12 women shoe size. They can be machine washed and are extremely durable while being cost effective.
I ordered the socks based on their colour and design symmetry. So far my socks have been through multiple washes and still look new and user ready. I wear them daily because of their amazing fit and plan to buy more as Christmas gifts.

Love these socks!
Fit Type: Classic Fit, Color: Black, Size: Large
They are a little on the thin side, but that is how I like them. Thin, comfortable, breathable, but still sturdy. They work great for me and I have bought them several times for me and my kids over the years.

Thin
Fit Type: Classic Fit, Color: Gray Assorted, Size: Medium
I bought these thinking they would be slightly thicker material. They are thin but don't make my feet sweat working outside in the heat while wearing them during my work shift. They are comfortable and stay in place so I don't have to keep fishing for them inside my shoe to move them up a bit.
The one thing I wish they had was the support band in the middle of the foot.

Super comfortable
Fit Type: Classic Fit, Color: Black, Size: Large
Love these socks. They are very soft fabric but also heavy so they are very durable. And the price is far cheaper than any of my local stores.
