It's difficult to find slippers that can be adjustable and machine washable. I prefer open toe design. My favorite brand WAS Acorn, but a few years ago, they "did something" to the way they are made. Now Acorn is more stiff. So, wanted to try this brand. (I'm pretty sure that I received a returned pair, as they looked like they'd been worn, and there was no tag attached, like there usually is with other brands. I decided to wash and keep them) So far so good. The velcro closure works well enough. I would just call them Good enough
