***Update***I purchased the -W111-LGY_Women 9 B(M) Atika Womens Maya Trail Outdoor Water Shoes. I was unsure. The mute capability doesn?t actually mute it. The truth is that it blocks mainly background noise, like groove or other noise. I never like giving a bad rating. But for the price, I feel crocks sandals should come in half sizes. No real arch support if that is what you are looking for. She had no choice. The bottom is a hard rubber sole, perfect for wearing around on slippery floors. But just turning it around doesnt really completely fix the problem.
