I bought them in black and I like them so much I will be buying the brown soon. They fit true to size and are comfortable and stylish. I like the clean simplicity. They're basically a dressy sneaker which is perfect for my job's 'dress code'. Yet they're stylish enough to be worn weekends or a night out. They seemed just a touch stiff out of the box but IMO that's completely normal and fine - after just a couple days of wearing them they are breaking in nicely. No complaints on that. They seem to be of very high quality and I'm very happy with them.
