The Sport Lightweight Hidden sock pairs a barely-there feel with Injinji’s signature five-toe design. The five-toe fit actively reduces friction and prevents blisters in low-cut shoes, while also encouraging natural toe splay and supporting total foot utilization. Its lightweight, breathable design ensures comfort and manages moisture, while the silicone heel grip keeps the sock in place for slip-free comfort. Perfect for low-cut shoes, this hidden performance sock is a must.
