The blue palette and the 3D optical pattern immediately look imaginative: the Happy Socks Filled Optic Blue combine several shades of blue for a spatial effect. Combed cotton with an admixture of polyamide and elastane is soft to the touch and at the same time resistant to normal wear. The unisex cut fits both men and women, and the choice of sizes is clear. Wear them at home when relaxing, with a sports outfit or as an inconspicuous color detail for smart-casual combinations. They go well with jeans and sneakers, they will add liveliness to the outfit without exaggerated effect. The material holds its shape and provides comfort throughout the day.
