This is the first time I've worn the Arroyo's; I'm not impressed.  They fit comfortably but they don't seem as durable as older Keens I've owned.  The cord snugging the sandal up isn't elastic, but rather regular cord that doesn't stretch.  The tongue isn't attached the same way other models are and there's a noticeable tendency for it to tuck under the sides of the sandal as you're pulling it on.  Because of the fit and poor quality I'm going to exchange it for another model and hope I'm happier with it.  I have heard, however, that once Keen went public with their stock the quality of the footwear has suffered.
