Introducing River Styx, created with Deathless Thread, 20 times more durable than a traditional athletic sock engineered specifically for skateboarding. The Deathless Thread is placed in strategic high abrasion areas of the heel, toe, and lateral foot, a.k.a. Ollie section. By twisting the Deathless Thread with our fusion yarns we created the ultimate blend of comfort and durability to keep you pushing in the streets, parks, and anywhere your board takes you. Gone are the days of the blown out socks.
