Definitely chunky, on par with a Birkenstock in bulk, which I like. I wish they have black in my size, as well. They are incredibly comfortable, even more so than the Mephisto Helen. I hope they make them in more colors next season.  2 months later: I gave this a 5 star when they were new. Now 2 months later, the insole of one shoe is starting to unglue in 2 places!!! The ankle strap on another shoe has started to move around while walking making the shoe uncomfortable. I am very disappointed with the low quality. I am not sure I will ever buy this brand again. I expect a whole lot more from a pair of shoes that retails for $250, even though I bought them on discount.
