{"product_id":"franco-sarto-womens-flexa-solene-knee-high-boots-nw-ob","title":"Franco Sarto Women's Flexa Solene Knee High Boots NW\/OB","description":"Rooted in a rich Italian shoemaking tradition inspired by techniques originating from the University of Bologna, Franco Sarto pushes the boundaries of what a dress boot can feel like with the Flexa Solene Knee High Boot, the flagship expression of the brand's groundbreaking Flexa comfort technology. Expert artisans hand-stitch 7mm of luxurious foam directly into each shoe's sock lining, delivering cloud-like cushioning and a glove-like, contoured fit that moves with the foot rather than against it — all built on an ultra-light, ultra-flexible shankless construction for unmatched all-day ease. The upper is crafted from rich leather or suede with partially recycled eco-conscious linings, and a polished equestrian-inspired ankle strap with a circular buckle detail adds a refined finishing touch to the sleek, square-toe silhouette. A side zipper with elastic gore inset allows for effortless on-and-off, and the synthetic rubber outsole delivers reliable traction. The boot features a block heel measuring approximately 3.25 inches, with a knee-high shaft and a calf circumference based on published Flexa knee-high construction data sourced from Amazon (size 6M): shaft height approximately 20 inches, calf circumference approximately 13.4 inches; measurements increase by approximately 0.12 inch in shaft height and 0.20 inch in circumference for each half size above 6.","brand":"Franco Sarto","offers":[{"title":"10 Medium \/ Black","offer_id":52083077316906,"sku":"NWOB47056","price":89.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/3791\/5690\/files\/NWOB47056__1.jpg?v=1784156386","url":"https:\/\/www.shorelineshoes.com\/products\/franco-sarto-womens-flexa-solene-knee-high-boots-nw-ob","provider":"Shoreline Shoes","version":"1.0","type":"link"}
