Tried them out first on dry land for an evening. Nice and comfy. No blisters. Good sign.

Tried them out in water; they get very waterlogged. As such, they don't dry very fast either. Wore them in the pool this morning, poured the extra water out of my shoe just before ten this morning, left them out to dry and the shoes are still pretty soggy at five this evening. Not the end of the world, but glad I tested this before packing for vacation, now I know to plan for them to stay pretty wet and not be an all day shoe. Hang on to the bag they come in, bigger sizes won't fit into a zipper bag and they'll soak your gym/travel bag if not contained.

They're comfy, easy on the feet. Definite spring in my step during water aerobics class this morning, and kept any germies off my feet too, both in the pool, on the pool deck and in the shower.

Others mentioned slipping. I don't think these are very slip-inducing. Certainly less slippery than worn out crocs or crummy flip flops. If you're an old woman, you have a greater chance of slipping no matter what, don't blame the shoes. I'm not an old lady, and I'm not naive to think that a pair of shoes will prevent a fall. Just use some common sense and you'll be fine.

Sizing. Does seem a little bit big, but when you have big feet, you pick a big size. I think the next smallest size would be too small. Doesn't really bug me much. Better than too tight.

Good first pair of water shoes. I didn't want to spend a ton before I knew how I'd like wearing a shoe in the water. I'm happy with my choice. Glad they're not really ugly like some water shoes out there.
