If you like to run or walk a lot I highly recommend you to try Fengda Air Slip-on Mesh Comfortable Lightweight shoes.
They are very fresh for the hot weather and the most important is that they are very comfortable. They are great for the beach and water activities. They come in several colors. They fit right size and you feel you don't have shoes.
If you are looking for shoes to do yoga and pilates this is a must to have in your closet. I like the dark blue to match with my sport clothes. I'm ready to start my workout routine.
