Went for a long walk at the park in my leather flip flops and was also barefoot for awhile. So much filth and dirt on my cute little flip flops! The bottoms are soiled and the foot beds are SO nasty with dried foot sweat, grime and foot funk. I love walking barefoot everywhere, and I often turn to these shoes to slip my feet in after--you can literally see my entire foot sole and toe prints from so many months of foot crud! Time for my little bitch to suck these clean!!
