Pretty much every pair of Sketchers shoes now has memory foam soles and everyone seems to think they are great but I hate them.
They are really hot, the foam is like a layer of insulation.
The top of the memory foam soles is somewhat elastic so it's really smooth and slippery so your socks slide around inside
They are no more comfortable than regular shoes and in fact I think they provide less arch support since they are squishy compared to shoes with harder foam.
And most of all the memory foam gets smashed and wears out in no time with some shoes having the foam glued in so replacing the insole is impossible.
I don't have am answer why, but my feet hurt like hell after a day of standing around or walking without the memory foam. I'm trying to find a good pair of professional looking shoes that fit like Sketcher memory foam actually.
I haven't used theirs, but I've got On Cloud shoes (one of those with double layers of dampening) and Adidas 4D / 4DFWD 3D printed mesh shoes, and both are really soft and stable simultaneously and work very well. Although they're also both on the expensive side too.
