I ordered these and they arrived within about two days! They are very comfortable and, most importantly, WARM! Because of the thickness of the sole, your feet are off the ground enough so that the cold doesn't seep through if you have stone floors (or other cold flooring material). They don't hold your feet (i.e. they don't come up at the back) so it is very much a slip-on design, but that is fine - not a problem. The one thing I would advise is to buy a size bigger than normal. I am usually a UK size 4 (37) but as I have had Isotoner products before, I knew to get a bigger size, so I got a five and they are just right for me. The design is pretty, too. All in all, worth the £18 (?) that I paid for them.
