At Vionic, we’re disrupting the footwear space by transforming how people view shoes - from walking shoes to slippers and everything in between. It's not very often we come across a brand that helps to bring balance to our lives. Many of our products are recommended by the APMA, or American Podiatric Medical Association, providing stability, flexibility, cushioning, and arch support in every pair. Vionic was created by scientists who have proven the notion that balance begins with our feet and moves throughout our body. Our VIO MOTION technology is the fusion between dynamic movement and grounded stability solving whole body balance. Our shoes help reduce common foot pains associated with over pronation, and plantar fasciitis. Our shoes will help you walk through your day without sacrificing style.
