I agree totally with Alison's review.
I bought my original pair of these in 2006 and they lasted forever - even making it to the top of Kilimanjaro with me where they were fantastic at keeping my feet warm at the end of every days trekking. I also lived in them around the house, much of which has stone floors.
I eventually threw them out at the end of last year when I "treated myself" to a new pair. Big mistake!
The new pair, purchased in November, are awful. The soles had worn right through in three places by February. I really wish I'd kept my old pair which had no holes in the soles despite everyday wear for almost 6 years.
These slippers are definitely nowhere near the quality I was expecting or the quality they used to be and I will not be buying them again.
