I have to say also that my SmartWool socks have held up for years of wear, and have not lost their elasticity or good looks, even without TLC. I machine wash and dry them (but hand wash and hang dry probably makes them last even longer, as flaneuse mentioned). They come in such wonderful colors and patterns now, and are so warm and comfortable. Add to that they are readily available and I can usually find them on sale. They are a great buy for us value-minded people with cold feet!
