Preamble: (1) I bought four pairs of slippahs to settle, finally (or at least for the moment!) whether any are really worth $30++, or, rather, if I'm going to spend $30++, which is worth it! (2) I'm specifically talking about size 16s. These points may or may not apply to Normal Size people. I'm ecstatic that shoebuy had any 16s at all, let alone a choice!Good bit first: The strap on these sandals is *wonderful*. I might even use the word "amazing." On that strength alone, I'm keeping them.That said, I was surprised (since they're New Balance) to find them not very supportive at all. They are very thin soled, and -very- light: This could be a bug or a feature, and only time will make that distinction. If they wear quickly, I'll be disappointed. But, it could be a great feature for certain uses: Gym bags, backpacking, keeping onboard for post-sailing dock walking, etc -- they are -strikingly- light, and thus would go almost unnoticed in your gear bag.And, man, is the strap comfortable in a way that somehow combines "vanishing" and "wow, soft." Yeah, I think that bumps them from the 3 I first set to a 4.The NBs are comfortable, but not particularly supportive, and light/thin, but only time can tell if "also durable" or "wear out quickly" applies. So, of course, I kept three pairs. We'll see how they do.See other reviews for specifics on each.
