Have not worn them for longer than 2 hours, out doing errands, but they are super comfy and very light weight....and so stylish. They are true to size too. I have not worked out in these shoes yet, hopefully they will be my new fav running shoes. A bit pricey but I got 20% off by signing up for amazon shoe promo emails, so feel ok w/the price. Also shopped around so I know I got the best deal on amazon.

*UPDATE* I have worked out in these a few times (doing an indoor exercise routine) and they get my approval. Worth the price.
