REEF Fanning Mens Bottle Opener Sandal 13

Now that I have finally found a pair that are fit right, these sandals are great. The are very comfortable and seem to be a good quality. The built in bottle opener is a neat little perk. Only time will tell how they hold up. (See my update below) So I don't know where Reef gets their foot size dimensions but they are obviously a bit off. To start, I wear a size 9.5 Men's in pretty much every pair of shoes AND SANDALS I've owned for the past 25+ years. It's pretty consistent. I could probably wear a 10 in some brands, but 9.5 usually works once worn in some. Based upon numerous reviews on here, these sandals run small and people recommended ordering a size up, so I did. Holy crap the size 10 sandals were enormous, I put my foot in them and the amount of sandal sticking out passed my heel could likely be considered a reversed swim flipper. No lie, it was at least 2 inches passed the back of my foot. The strap placement and toe area were close to correct, but still too large. Figuring this was a fluke of some kind, I then ordered a size 9. Guess what, the size 9s are EVEN BIGGER than the 10s were, by a good half inch. It made absolutely no sense. I've already returned the 10s, so I can't take a comparison photo at this point, but the 10's were a solid half inch shorter than the 9s. Someone please explain that. So I tried wearing the 9s around the house a couple days to see if I could get used to them, but I just couldn't. It was like a never ending flat tire risk with those things. I would have to walk 4 feet in front of someone to avoid getting tripped up. So finally, I ordered a set of size 8s, which in theory should be WAY too small, especially considering everyone said they run small. But they are PERFECT. Perfect toe placement, perfect strap placement, only about a 3/4 of an inch passed the end of my foot. Perfect. Obviously that means something is wrong with this sizing too, but at least I found the size that fits a 9.5 foot. Now I have to attempt the return of the size "9s". So yeah, once you land the correct size, they're great. Good luck when you order. May the odds be in your favor. ***5 year update*** So I've had these sandals for nearly 5 years now and they are still great after wearing them basically daily from mid-May to late September. They're still super comfortable to wear and fit great. They are showing some decent wear on the bottom, but so far they haven't become noticeably slippery. I mean, how can you complain about heavily used sandals that still function perfectly after 5 years? I'm planning on buying another pair now just because these aren't the prettiest anymore, but I'm sure I'll continue to wear them frequently until they eventually give out. Still a Reef fan, no doubt.
