The Gatta Footer 13 are extra soft socks in laser cut technology, with extremely flat seams. The socks are cut low so that they are invisible in ballerina flats. The socks also have a silicone strip so that they stay where they belong and cannot slip off the foot. A very nice basic this summer for ballerina flats.Transparency: OpaqueSpecial feature: deep cut, laser cut very flat seamsPattern: -available colors: beige, blackMaterial: 74% polyamide, 26% elastane
