I think when it comes to comfy socks, both cashmere and wool have their own special appeal, but they do offer different experiences.
Cashmere is often praised for its incredible softness and luxurious feel. If you love the sensation of slipping into something super soft and cozy, you might find cashmere socks to be the ideal choice. They're especially nice for lounging around the house on a chilly day. You can see good examples on this website.
On the other hand, wool socks are known for being durable and great for warmth, making them a reliable choice for everyday wear. Wool naturally wicks moisture away, which can be a big plus if your feet tend to get sweaty. This feature helps keep your feet dry and comfortable during longer wears.
In deciding between the two, think about what matters most to you. If you prioritize softness and don't mind the extra care, cashmere might be your go-to. But if practicality and durability are more your thing, wool could be the way to go.
