stiff like cardboard tops of shoes
Size: 5.5, Color: Natural Nbpu
These shoes are good enough quality and cute cute - even fit great, EXCEPT the faux leather top (part that encircles your leg) is so stiff, that when you walk, it cuts into your leg like hard cardboard making it difficult to walk comfortably. I do like them otherwise, but can't stand the hard, unbending top of these shoes.

Great for wide feet

Beautiful- great for wide feet, camouflage slight swelling in feet / ankles beautifully. Look great with everything; adds a touch of elegance & rock star. Super fast shipping too!

Sizing.
Size: 10, Color: Natural Nbpu
They run big, I usually wear a size 9 wide, but since they didn't come in a wide, I chose a 10 and they fit comfortably width wise, but they were too big otherwise. I would recommend letting viewers know if it is a wide shoe to let buyers know, to better serve the customer on what size to purchase, other than that, I loved the shoes just wish I could've kept them and worn them for my event.
