Product title: FRYE Women's Shirley OTK Riding Boot
Product description: FRYE turns in another gorgeous leather look with the Shirley riding boot. We wish the sleek, buttery smooth upper would never end, it's just that gorgeous. Luckily, it goes a long way, extending over the knee for extraordinary leggy fun. A touch of detail behind the calf adds a flourish to the silhouette making this a look you want to showcase full-length., The Frye Company is the oldest continuously operated shoe company in the United States. Founded in 1863 by John A. Frye, a well-to-do shoemaker from England, and family-run until 1945, Frye products have a long and illustrious history. Frye boots were worn by soldiers on both sides of America's Civil War, soldiers in the Spanish-American war, and by Teddy Roosevelt and his Rough Riders. When home-steading drew adventurous New England families to the West during the mid and late 1800's many of the pioneers wore Frye Boots for the long journey. Today Frye remains true to its roots with its line of heritage boots, but continues to innovate as it introduces chic new handbags, pumps, and sandals to its collection.
