Blue is the easiest colour to get wrong in a sock. Go too bright and it reads like an attempt at personality. Go too corporate and you’ve essentially disappeared from the ankle down. The sweet spot is a blue that works hard without announcing itself, something that sits well against grey trousers, holds its own with navy, and doesn’t make a casual Friday outfit look like it’s been over-thought. We’ve been looking specifically for options in that middle register. Proper cotton and merino blends that keep their shape after washing, a weight that sits properly in a shoe without bunching, and a shade of blue that earns its place in the drawer. Nothing novelty, nothing with a logo competing for attention. Just well made socks in a colour that most men actually wear. The kind of thing you buy once, wear constantly, and only notice when you run out.
