I got these for my husband who wears through slippers faster than anyone I know. He wears slippers indoors and outdoors so a good sole is essential. These were on offer at the time and at that price were worth a punt. They have been great; they stay on his feet, they have a comfy insole and the sole is rubber (I believe) so not slippy and doesn't soak up water from the ground when taking the wheelie bins out. They are full price at the time of writing, but I'd still buy another pair for him when he wears this pair out.
