I owned a previous pair of very similar shoes from Skechers that I bought around 2005.  I used them for work in a business where I walked a lot, stood almost all day and climbed ladders.  After a few months I ended up with a foot problem due to the complete lack of arch supports.
I got custom insoles from my doctor with the proper support and used them in those shoes until my new puppy ate the shoes a couple of weeks ago.
These new ones are much lighter and have better construction around the heel, but have the same support issues.  They are large to the point where they slide around on my feet even with socks.  So after walking in them for probably 10 miles on hard sidewalks, I put the old insoles in them and they are now almost identical in fit to the old ones, just not worn out.
I like the slip-on design and they are better for my feet than the Hawaiian flip-flops I would otherwise wear in the summer to walk in, with the insoles.  Without them, they are too loose and the insoles are just too flat.

These should not be sold as a "walking" shoe, but as a lounging shoe.  Great for sitting around and doing things around the house.  But without some sort of pronounced arch support, they will hurt your feet if you walk a lot and they are too sloppy of a fit for walkting very much.
