The Thunders Love True Blue socks are the expression of our hydraulic resources, from huge oceans to wonderful lakes, including rivers, seas, and waterfalls. However, they also are inspired by the ground which is constantly affected by chemical spills. These chemicals along with fertilizers and pesticides, oil spills, sewage, and overfishing are causing a huge pollution in our most valuable resource: the water. In the commitment to preserving this precious resource, Thunders Love has chosen to use recycled cotton. This vegetable fiber does not require the use of water during its production. In these socks, recycled cotton yarns in light brown on the outside have been used. However, it have been opted for three tones of blue inside, representing the variety of hydraulic resources offered by our planet Earth. These different blue tones can be glimpsed from outside, getting a fusion between land and water.
