Excellent shoes for what you’re buying them.
Size: 12, Color: Black
My 2nd pair of this brand. These are awesome. Easy to come off and get on. They stay cool in the summer, they are comfortable with or without socks. I use them in lake and pool, and they still look new. Very inexpensive, and for a change they look actually nicer in person than in the photos. I dont know how they would be doing any athletics but for everything else, including walking a lot and standing for hours, they worked great.

Surprisingly awesome!
Size: 10.5, Color: Dark Gray/Beige
I have only been wearing these for a few days so I may have to revise the review over time, but so far these shoes are absolutely outstanding. If you owned and enjoyed the original Salomon TechAmphibians, later ruined with new designs by the maker, these are their natural heirs. I took a chance on these shoes since the design is very similar. They are lightweight and comfortable and they provide great footbed support whether loose or tightly laced. Like the early TechAmphibians, they also have the cool feature of a collapsing heel upper, allowing their use as slides. They are also half the price that the Salomons sold even 10 or more years ago. The sole has an aggressive tread pattern and is quite grippy wet or dry.
I measure as 10.5 D on the shoe size device but almost no shoes in that size fit me in the last few years. I got the 11-11.5 size first but it was swimming on me. 10.5 fits well with a bit of extra room so I can wear them with or without socks.

Great shoes
Size: 10, Color: Grey, Size: 10, Color: Grey
I got 2 pairs of these specifically for a water rafting trip. The first pair was a little large, so I went down a half size ( and gave the larger pair to my son). They are comfortable, even for wide feet - although after a long day of use in the water, there was some chaffing on the outsides of my feet. It loosened up a bit across my wide foot, after getting wet.
These worked great! They have adjustable strap across the back, that pulls tight on the outside.
the laces are elastic and tighten by pulling and then pushing the stopper down onto the laces. They didn't slip (loosen) but, to get them tight, I had excessive amount of laces hanging out (had to tuck them into the tongue.

Exactly what I was looking for
Size: 9-9.5, Color: Black Denim Blue
Perfect for what I wanted in an active casual shoe. Love the tread, it's both grippy and durable but flexible, the fit, adjustability, easy to take on and off, perfect amount of cushion and stability. Can wear with or without socks comfortably.

Excellent value!
Size: 10.5, Color: Black
Very well Made. Just received these and was surprised at the quality of the materials and they way they look. Much higher quality than the oriental point. They are comfortable and fit very well. I ordered 10.5, nice room in the box. I have not worn them yet, first impressions are positive. I will update after wearing them for awhile. So far, very happy with the purchase! Black and orange color looks great!
