The sandals are ultra comfy. Now these are not expensive shoes and I power walk almost every day about five to six miles but in three months they should still be in good shape. Great product, very durable! I should add that my bike is 30+ years old, and very difficult to find/buy a 26" tire and tube for. Real sparkly! Nice looking sandals. I put them on and gave it a spin. Shipped same day, communicated great, responded quick, made my return completely hassle-free. I am not sure about the Android platform. For me the shipping was fast and my heart felt better doing this for him.
