Vionic Uptown Willa slip on shoe. Vionic Shoes are designed with VIO MOTION TECHNOLOGY, providing stable, cushioned, and flexible support with arch support. This technology helps correct pronation and promotes proper alignment, reducing heel pain from common conditions like plantar fasciitis or achilles tendonitis. Proper maintenance of your Vionic women's and men's shoes is important - wear them for a few hours to adjust to the support, gently wipe with a dry, cotton cloth to clean, and avoid submerging in water.
