Premium Men's Dress Socks - Lightweight Rayon Bamboo Fabric with Contrast Heel & Toe - Comfortable Formal & Business Socks for Office, Wedding & Dress Occasions

These are among the most comfortable socks I have ever owned. The rayon made from bamboo is soft as silk and breathes well. This is the second time I have purchased Sierra Socks and they wear very well.Good qualityThe socks immediately fall down (walking less than a block). I bought some bamboo socks years ago and they are wonderful as they stay up instead of sliding down to my ankles. These socks however fall down just like other (non bamboo) socks I have used.Best sock that I have ever ownedSocks are comfortable and do a good job keeping your feet dry. The main downside was the durability. The lifespan of these was lacking compared to a few other dress socks I've owned. Overall, still a solid product.
