Merino wool is naturally thermoregulating, which means it keeps you warm in cold weather and cool in warm weather, while preventing overheating and clamminess by absorbing and releasing vapor. It’s also naturally antibacterial and odor-resistant, making it a great choice when you need an extra day or two of use before your next wash. The addition of nylon takes the durability up a notch, and the touch of Lycra adds just enough stretch. Light cushioning under the heel and toe areas provides support where you need it, while lighter mesh weave on the top improves breathability and fit. Plus, added arch compression creates a secure fit and improves comfort. The Drop logo is placed on the toe box, so you can see it whenever your put your socks on.
