Donkey Label socks are awesome and my leading choice for cycling kit. The binary design is cool (still trying to figure out if it actually says something in binary code). Fit is perfect and they are comfortable in warm or cooler weather. However, I did notice that compared to the numerous other socks I've ordered, they are much more slippery so you have to walk very carefully until you can get your feet into shoes.
Yeah, my wife got mad at me for these socks. The minute she saw them on me she wanted to know why I didn't get her a pair. Off to the stable for more provisions.
