After wearing these for a few weeks, I am no impressed with the memory foam nor the foot support offered by these.<br /><br />Problem 1:  The memory foam is skimpy and does not return to shape well after wearing.  In other words, you wear them in and the memory foam is of little relief support for your foot after a few weeks.<br /><br />Problem 2:  I expected to have good support for the foot and relief from pain from standing.  Nope.. these do not do the job.<br /><br />Problem 3:  They quickly turn stale and develop foot odor, even for someone like me who wears socks with them and do not sweat much in the feet.  So, yeah... once again... a stinky slipper after wearing.  And I'm sorry, but these will not hold up well to any sort of machine washing.<br /><br />As a plain slipper, they are as good as about any other slipper. But for foot support, and regular use, these are nothing special at all.  So I have pitched them and replaced them with a pair of Vionic Jon Mens Slip-on Orthotic Sandals, which are awesome.
