The good: Even though they arent rubber, they are thick and foam all the way around so I dont imagine them getting holes in the sides or bottoms, at least not very easily. Very comfortable and fit my almost wide foot with a little bunion perfectly. Everything else is brilliant. Sonys LDAC is a bonus. Die damals bestellten Comfort-Adiletten hatten eine zu weiche Sohle und viel gewichtiger, die Lasche war viel zu eng, so dass trotz einer Schuhgröße größer als üblich, die Schuhe nicht gepasst haben. ) was a little stiff at first, but almost immediately I started feeling it give. I was hesitant with these Birkenstock sandals as they werent like any of their other shoes. It all worked out. I also don’t see them breaking down anytime soon like most slippers. I have plantar fasciitis, and this brand is the only one I can wear and still walk.
