I love these things. I wear them until the sole is slick and run down! I put another kind of insole in. Size 11D fits me perfect.  My old Army feet hurt too much in other shoes. I have two pair, one a year older and I rotate through them. Im here to buy another new pair! I use them like shower slippers on trips. Just one pair of shoes...

Five Stars! Keep making them!  And don't change anything!
