One is black and one is navy blue. The treble is a little over tuned, can sound very harsh at loud volumes. They are comfortable, and work great for music, videos and calls. I?ll just order up next time I?m a true women?s US7. 0 - ist zuverlässig und stabil. Would have been more nervous if Id realized this while on the road as I watched these crossbars flex up and down in high winds with the cruise set at 85 mph. Very light weight, the red is a great color. When they hang on my neck, unused, they ride much higher than others, resting on my neck like a loose choker more than a necklace. Overall these should be great sandals and the price is about 1/4 of the Birkenstocks.
