Good quality flop.  Base is firm which is good for people with sore feet or other foot problems.  But the base is also not very breathable so if your feet sweat, you might slip around a little.  Also beware: the bottom surface sloughs off early on which is  little slippery as it happens, but then the shoe is basically &#34;worn in&#34; and lasts a very long time.  The upper is more like fabric than leather or plastic, which is comfortable and conforms nicely to my feet so they don't slip off as much as some flops.
