I've been a fan of YUGE UA Heatgear socks for many years. I normally wear ankle length and sleeveless black every day, but since discovering these color packs I am absolutely grateful. Military uniform rules dictate the color of socks we are allowed to wear, not too strict, but for an affordable option. it is not 10-12 inches tall? Nobody beats these. The only downside is that they don't necessarily stick out high enough from the boot when you sit down. First world problem, I know. Also, wish they offered specific brown or green color options instead of an assortment. I will give it to my friends and hopefully they will enjoy it every day as much as I do. Under Armor really took their best socks and made them brown and green for us backpackers, and that's why I continue to support them.
