I have had a few of these shoes, Most recently the silver with the gems on them. I love them, I do size up due to being a wider foot. There is a short 1-2 week breaking in period. But once they are broken in they are fine. I wear them pretty much all day and even recently wore them to Disney after my tennis shoes caused a bad blister (they were broken in too but for some reason just made everything worse). They were comfortable the whole time!

For those having issues with breaking apart - if it's happening right away then definitely talk to the seller but after a few months of general wear and tear on the shoes (I am in mine for probably 12-14 hours a day) will cause the sole to start lifting and might have the padding coming up. Shoe Goop (sold in lots of places) will fix that and it's water proof. A small tube will last a long time and is a great investment for all shoes!
