The description at the time of writing this review still says "according to size". They would POSSIBLY fit me a whole size up. So from ladies 8.5 to 9.5. I have NEVER worn 9.5 shoes. The durable yet sturdy rubber leaves no leeway when it comes to the toe box. In fact if you look there is THICK rubber. So if you have more than one narrow toe, you're in trouble. Very disappointed with all the bad shoe information on the internet. It's very difficult to find the right size without going to the store.
