Socks perfected by science, for the planet ♻️ Save the planet in stride: you’re wearing polyester made from recycled plastic bottles. Initially launched as a limited edition collection, these socks were so loved that they are now here to stay. We haven’t changed our quintessential Strideline technology for these socks. We’ve just gone even greener by reclaiming plastic from our oceans and repurposing it into socks. Make your feet and the Earth more comfortable this season. Features * Recycled Polyester made from recycled plastic bottles. * Quad-Ply Yarn™ Padding around the medial and lateral arches of the foot. * Strideline Heel Strap™ for flexible ankle movement and support. * Direct compression to promote circulation. * Zoned cushioning for cloud-like comfort in all the right places. * Contour-fit thanks to stretchy shape-memory polymers. * Moisture-wicking via mesh vents and hydrophilic fibers. * No stank = no worrying when taking your shoes off.
