Falling temperatures require more calculated steps towards layering before setting out on your next ride. The Giordana Merino Wool Tall Socks feature a tall, 7-inch cuff (nearly 18 centimeters) that layers comfortably underneath the cuffs of your winter tights, and should extend past the tops of most shoecovers as well. Giordana uses a premium New Zealand Merino wool that is warm and lightweight, highly breathable, and exceptionally soft -- these are all excellent qualities for cycling, and equally suitable for those off-days at the office too. As we've written before, wool doesn't have to be scratchy. Merino wool is soft and comfortable. But in terms of overall use, durability and ease of care, 100% Merino isn't desirable. Giordana spun both nylon and Lycra into the fabric blend to ensure these socks will not wear out, or stretch out after extended use. Just remember to wash them on warm, and tumble dry (or simply hang them, as they should already be somewhat dry right out of the washer), they'll do fine. The Giordana Merino Wool Tall Socks are constructed from a blend of Merino Wool, nylon for added durability and wear-resistance, and Lycra for stretch. You'll have two sizes to choose from: Small/Medium, which fits shoes sized 4. 5 - 8. 5, or Large/XL, which fits sizes 8. 5 - 13.
