Zen Markt socksThese solved several problems for me that I didn't know could be solved. I attend an informal dance class where I dance in sneakers, which means when I try to pivot, I can't, and when I slide forward on one foot I'm prone to stop short and so risk falling forward onto my face. These sharp-looking socks slip onto the front of my sneakers around the ball of my foot and let me pivot and slide - instantly more fun, and they stay securely in place. I hand wash them. They are a very firm weave and hold their shape. I can't tell apart the worn pair from my new, unworn pair.
