With a mesh upper, elasticized double-straps across the vamp and a lightweight EVA footbed, this style stands out in a handful of vibrant hues. Vionic active footwear features Advanced Motion System (AMS) technology, combining our podiatrist-designed orthotic with a flexible, cushioned outsole and a lightweight, breathable upper. Step into support for work, play and everyday. Recommended by Dr. Andrew Weil. Snug fit: We recommend sizing up by a half size. Available in women’s whole and half sizes 5, 6-10, 11. Fits medium (B) widths. For the greatest comfort, we recommend wearing your new Vionic footwear for just a few hours for the first few days to allow your feet to adjust to the new level of orthotic comfort and support. Within one to two weeks you should find the product completely comfortable and supportive. To clean, wipe with damp cloth and air dry under indirect sunlight only.
