Good buy, great fit!
Size: 12, Color: White
Very satisfied with the fit, style, and quality of these shoes. Usually scared to buy shoes online due to the sizing issues or difficulty. These were no sweat. Good delivery as well.

Doesn't really slip on too well.
Size: 11, Color: White, Size: 11, Color: White
Doesn't really slip on too well. Also, since the heel is ridged it unintentionally allows my heel to slip out while walking.

Really like these for casual summer outfits
Size: 10.5, Color: White
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.
