Product title: Donald J Pliner Women's Sandora-R2 Riding Boot
Product description: When the feet are uncomfortable, so is the mind and body. With these words, Donald J Pliner has committed his life to the quality and perfection of an innovative line of shoes. A life-long and family tradition is continued with his luxuriously comfortable footwear that never compromises creativity or fashion. Visionary designer Donald J Pliner launched his line of luxury footwear and accessories in 1989, and immediately established a reputation for innovative design and high style for both men and women. Pioneering new materials, such as stretchable micro-fibers, he also brought unprecedented comfort, flexibility, and lightness to footwear. Born into a Chicago-based family shoe business, life at DJP is also a family affair. Creative director Lisa Pliner, Donald's wife and frequent model for the innovative ad campaigns, works side-by-side with him to develop each new collection, inserting her artist's vision into the designs, colors and textures. And the Pliner's pure white Maltese, BabyDoll, is ever present, inspiring her own clothing line for the past three years. Today this global brand, manufactured in both Italy and Spain, has established an almost cult following among people who were originally attracted by the fashion-forward style, but return again and again for the comfort and craftsmanship.
