These Rothy’s have a rounded toe, removable insole, and are made of a knit material from recycled plastic bottles. They are washable, with a soft flexible upper. They don’t have much stretch so if you are between sizes you should size up. These are size 8 and have been worn and washed a couple of times. I just washed them before posting. These are gray with blue accents at the heel. This color is no longer available on the Rothy’s site.
