These are really nice kicks. Stylish, comfortable, and eye catchy for sure. Not too heavy, good price, and fit well. These are great, casual white shoes for a summer outfit. I gave it 4 out of 5 stars as these do pick up and hold onto dirt and smudges more than I’d like to see. Yes, I know, white shoes are magnets for this stuff, but these tend to scuff and discolor more than I would have assumed. I live in an area with lots of bad weather most of the year so I only get a chance to wear them for a few months of the year unless I want to brave the wet and muddy weather. If you live in an area that has lots of sun and are willing to put these to the test and clean them often, I would say go for it.
