I purchased these from the Kickstarter a few years ago. I have worn them every day for a week, about 9 hours at a time. Very comfortable!
They seem very sturdy and while they stretch, they dont 'stretch out'. I love the little bump you get from the hidden small heel. I was worried about them slipping off my heel but I have had zero instances of that happening. I ordered an 8.5 but probably could have gone to an 8, but I will say they run mostly true to size.
Only gripe is the pink strip. It clashes with just about everything I wear.
