After reading dozens of reviews of other slides, most of which weren't very flattering, I settled on this one. I think other reviews of these slides have been mostly positive. I would like to buy a more expensive pair. The foam they are made of is very hard, almost plastic. They don't give my feet any support in the arch. Hard foam is like walking barefoot in a tree. I wear 12.5 shoes, bought them as a 12 and they dangle a bit in the arch strap.
