UPDATE 30. The memory foam insole rises from the sides to a low mound - in other words, the insole is rounded. Pretty nice design, welding and materials used here. Don’t Buy! 2 stars in the meantime. I’m very pleased with these and also with the cost since so many organic products are so much more expensive, but these aren’t. Bolt heads (hex) are loosely made. It wont hold touch up cosmetics either. Notes lower than a guitar are effectively lost. I like the white sandal because the color scheme seems to be a good mix.
