Black Suede Block Heel Over The Knee Boots Tracking down the perfect black knee boot just got a whole lot easier, thanks to Kurt Geiger London's chic new Tring silhouette. Taking the essential high-leg trend and respinning it with a wearable 85mm block heel in durable rubber, this elegant design features tonal stitching to highlight its architectural contours, a split back topline for comfort around the knee and an inside zip for easy on/off. Try it with a figure-hugging pencil skirt or slender shift dress for a thoroughly modern take on office dressing that'll take you from desk to dinner with ease.
