Further UPDATE: Amazon will NOT stand behind this product that bears their name (originally sold by Amazon.com, LLC). They did not reply to my emails (though they promised a reply in 12 hours- which never came) for assistance until I continued to contact them (nor did Old Friend) and I finally resorted to live chat. They patly refuse to assist me. They keep referring to the 30 day warranty period, which is inadequate at best. This is not what I have come to expect from Amazon, shame on you! At least I have requested that they stop selling this shoe. Be forewarned that this shoe purchase is a complete waste of your money; find a better shoe not sold by Amazon if you want any kind of replacement guarantee.
The chat is copied below.

Chat:
Sayed:I checked this order and I'm very sorry I'm not able to assist you because its too long to issue a replacement or refund.
Me:well here is what happened, a pair of the shoes, Old Friend, fell apart and I have contacted both Amazon and Old Friend to no avail. These shoes were defective and I want to at least advise you of this problem. These shoes were not abused in any way and are not well made it turns out. 2:09:42 PM
Me:Is there a way to submit a customer advisory so that Amazon will not continue to sell these shoes?2:10:15 PM
Me:and is there no remedy available to me for a product that should still be in good working order?2:10:40 PM
Sayed:I'm very sorry for the inconvenience, I would have surely helped you by giving a free replacement order or refund but as you know we can do this if it was before 30 days of receiving the order. 2:12:29 PM
Sayed:However, I will forward your feedback to the concerned department and they will take care of the issue. 2:12:57 PM
Me:well they were okay at 30 days which is not much of a warranty policy, i must say. I am sorry to hear that you will not stand behind your reputation and products that bear your name, I will update my review accordingly. 2:13:24 PM
Sayed:Is there anything else I can help you with?2:16:13 PM
Me:nope, typing the review now. 2:16:25 PM
Sayed:I've submitted a report to our products department and they will investigate on this issue. 2:17:06 PM
Me:okay, I have posted the updated review regarding the company's refusal to stand behind the products they sell. At least that may discourage further purchases of this product. Thank you for your time. 2:17:46 PM
Sayed:You're welcome. Thank you for contacting Amazon. We hope to see you again. Have a great day.

January 2011 UPDATE: FAILURE OF SHOE
UPDATE: These slippers that seemed so well made at first are now ruined. They had nothing but normal wear and tear and now one is completely opened at the toe box and side where the stitching and glue both failed. I am attempting to get an exchange or refund because for 6 month old shoes, this is terrible. The sole is also wearing through in that the tread is all but gone in several places where it has worn smooth. I WOULD NOT recommend these shoes any further.
I have downgraded my rating to 1 star from 5 accordingly.

Original Review:
After having and wearing this slipper for a few weeks now, my husband finds it to be extremely comfortable and durably built. The sole is very sturdy and quite suitable for wearing outside. We would buy this shoe again.
