These aren't the first pair of Clarks I've bought, but they are the first of the Wave. Run. They fit perfectly and are very comfortable. The bottoms are not flat, but have a wave so that when you walk you feel like you have a more fluid motion from heel to toe. I chose the blue color and the color almost reminds me of a washed blue jean color. They go great with jeans or dress slacks. When I first wore them the left shoe had an extremely noisy squeak each time you took a step which I found very annoying, but after an internet search I found that you can rub lotion on the inside of the shoe under the padding and into the side and in doing so it took care of the problem. I would have never thought to rub lotion inside! Clarks are so comfortable and feel wonderful on your feet. I highly recommend these shoes.
