First off, I do not run in these. I bought these shoes purely for casual wear, since I wanted a laceless sneaker to slip on. Therefore, take this review with a grain of salt as I have no idea how these shoes perform when used for their intended purpose.

As casual shoes, these have several strengths:
1. They're extremely light and comfortable.
2. They breathe very well; they're perfect for hot weather.
3. For laceless shoes, they fit quite securely.

However, there are definitely some negatives that you should be aware of if you're considering buying these:
1. If the weather is cold and/or wet, do not wear these. The same ability to breathe that makes them so comfortable in the summer will absolutely soak your feet within minutes in the rain. These are not water resistant in any way whatsoever.
2. They are not incredibly sturdy. I've worn mine for about nine months now and there is quite a bit of wear. They're about halfway between a solid, sturdy shoe and a disposable paper slipper.
3. The colors are just ridiculously loud. I opted for the blue ones, thinking they'd be a more solid blue, however they're very light grey and baby blue. I can't wear these with jeans without feeling utterly ridiculous. Actually, I can't wear them with shorts either, unless I pretend that I've just come from a run. Then I don't just feel ridiculous, I am ridiculous.

I do like them, overall. I just don't find them to be very practical for day to day wear.
