Worst buy ever.  Cheaply made - you will feel every pebble you step on if you wear outdoors... there is absolutely zero arch support and no padding on the sole - may as well be walking barefoot except they will keep your feet from being quite as cold.  They looked nice when I took them out of the package, but the second I slipped them on, I realized they are a complete waste of money.  I am returning them and spending more money on a quality product.  And they run large.  I used their sizer which says to go up one size - I wear a 12, ordered a 13 and can barely keep them on my feet.
