I love these socks. I have some Converse Chucks socks that have cotton in them, and they get stiff over time--not sure if it's the dryer. These are synthetic, so they wick better, they don't chafe, and they stay soft and silky-feeling. They never fall off my heel, and, while not invisible, they are, for all intents and purposes, no-show. I wear mine with Chucks and with my running shoes to the gym. I like the fluorescent stripes on these for fun, and to help match them up when they come out of the dryer.
