Our Bamboo Active Sport socks have been developed with two key features in mind, comfort and durability. Every Active Sport sock features an ultra-soft and padded foot, along with an arch support right down the middle to help fight foot fatigue. These Active Sport Tabs are low 'footy' style socks but feature a tab in the back to pad your heal from the back of your shoe. It also holds the sock in place to keep it from falling down into your shoes. That's right; these 'tabs' are designed specifically to stay up, and are the softest and most durable socks you'll ever wear!
