I also have to ask - what do you wear these things with? In the pics and everytime I saw them in the store I always remarked how spectacular they looked but I just couldn't picture how I would wear them. For weekend casual I sometimes wear dark denim super skinny jeans with my red neumoks but would never wear them to work. The Neumok was another example - I absolutely loved the antiquated olive and blue colors too but just couldn't see anything beyond casual use.
I wear business casual for work and have both the olive and the navy. Both the blue and the green go with khaki and tan. You can also wear the blues with gray or black pants. I suspect you could wear the green with black pants too with the right shirts.
