Originally I was worried my feet would slip out of them since there's no back to them, but that doesn't happen. All my previous slippers were the kind with a back. Now I like the fact they have no back because it makes them easier to slip into in the morning when I'm half-awake. I've had these slippers for just over a year now, and it looks like they should last awhile longer. My one big toe as worn a little hole through one of them, but that's not unusual for me (often happens with all my shoes). Otherwise, these have been fairly sturdy. I wear them around the house and occasionally go outside with them, walking on the pavement to put out the recycling or get the mail. The soles have a little wear on them after a year, but not much. They're rather comfortable too, although when it's really chilly I find I need to put socks on for more warmth. I would definitely buy a pair like these again.
