These shoes are very comfortable and appropriately sized.  The lining has a tendency to flip out when not wearing with socks.  Luckily though since the insert does come out it makes for easy washing.  So if you notice a smell from the inserts --- Just wash them on the gentle cycle and let air dry.

Only issue I have is that while walking a distinct "POP" can be heard.  Apparently the button bubble on the heel of the shoes has an air pocket.  When walking heel - to - toe it causes enough suction to occur.  No sneaking up on strangers or family members with these on.
