I love the look of these shoes and the colors.  Perfect for outdoor activities.  Haven't worn in the water yet but I am excited to do so.  At first I was a bit worried about the whole disc thing and it being too fragile and flimsy.  But it's actually a pretty cool design and it works well.  Of course I've only worn them a couple of times but as long one reads the simple directions first and adheres to it, they should be fine.  One twists it to the right to tighten it and just turns it a quarter turn for it automatically to loosen (almost like letting the air out of something) If anything changes then i will update this review.
