The next generation of our fan-favorite Devotion women's walking shoes features more rubber in the outsole for standout durability and grip, plus exceptional cushion and stability. The product works best by cleaning immediately after a spill by running cold water over the shoe. Use only cold water to remove the following stains: dirt, mud, coffee, ketchup, and blood. Do not wipe the shoe with any product, including water, as it can cause the stain to be absorbed into the material. Results may vary, and Ryka does not guarantee that this product will work to remove any stains, particularly after repeated use.
