These are almost as comfortable as the cotton soled ones and have become my regular casual shoes. The only downside is the smell of the sole - yuck. I expected this (from the reviews) and plan to buy more after these wear out. Until the smell dies down, I keep them on the porch. You just can't beat the combination of comfort and price. One more thing - the plastic is a bit hard, but softens a bit with use and scuffing.

These are the most comfortable slippers/shoes I own. As noted in some of the reviews, the soles are cotton so they don't provide much friction on smooth surfaces (I have failed a couple of dexterity checks on our wooden floors). They are my regular house shoes. I work out in them, too - but have to beware sliding too much.
