I have been buying Under Armour undergarments for years and have noticed a steady decline in quality. These socks are no different. I purchased another six packs of very similar styled Under Armour socks in 2023 and recently they have started wearing out. Those socks are no longer available for reorder, but these extremely similar socks were so I ordered them. The quality difference is obvious just by looking at and feeling them. They are more of a faded black/brown than the black pictured or the black that the three year old socks still are. The material is completely different and feels lighter. When wearing them they already feel like they are bunching up in my shoes, which the old ones never did. I do not expect these to last even a year and will not buy them again.
