Lettering came off bottom of the slippers

The second time I wore them the lettering came off the bottom leaving letters every where I walked. There was no traction.

I have been a satisfied Customer for literally decades.  I ordered my favorite slipper.  They are not holding up well at all.  I have identical slippers from 3 years ago that are still in better condition. :(

Within two weeks of buying these slippers the bottom completely separated from the rest of the slipper.
They were a good fit and very comfortable aside from that, so I am very disappointed.  I expected more from the name Isotoner

Received as gift, very cozy lining. After seconds of walking around the house the left slipper bottom started ripping off. Disappointed!

I am a stay at home mom who wears slippers all day long. I have owned 5 pairs of Acorn slippers and loved them all. So when I found this style I had to have them! The sad thing is within 4 months the fabric and soles were separating from each other on each one of the slippers. Sure they would last longer for someone who does not wear them as much as I did.

I love this brand but the slippers had a manufacturer defect - a piece of the foam came off along with the portion that holds your feet in place.

Bought these for my wife.  She likes them.  She wears out slippers fairly quickly so we will see how long they last.  They are called non skid, but really it is just some rubbery lettering on the sole of the slipper.  They are a nice lounging slipper, but if she needs something to wear around the house during the day she'll probably have to buy different ones.

These are cute and warm, but the sole of the slipper was torn to shreds after a month of wearing them! I never wore them outside, only in the house. The holes were so large that the foam started coming out, and I finally solved the problem by using black duct tape all over the bottom of the slippers. Not something I would expect to happen for this price.

I was super excited since I loved the print, however THEY WERE WORN! Seriously?! The socks were pulled and dirty on the bottom of the feet!

Edit: I returned this item and was appropriately credited.

I bought these because they have the non-skid writing on the bottom. The problem is they do not stay on! They are thin-medium thickness, cute colors. But they slip off if my son is not wearing shoes

I was so excited to find these slipper/socks! After reading the reviews, I immediately ordered some. They fit nicely, are very cute, and are perfect for summer. However, after only wearing them for a couple hours around the house, the "non-skid" pieces are coming off! We have laminate and tiled floors. I am willing to pay for something that will last, but these are not worth the money. Still cute, but much harder to walk in as I slide around the house.

The souls on the bottom have come off quite easily. The factory I work at is solid cement and may of wore them out quickly. I was surprised they came across so easily, as I am a big Brooks fan.

The first day I wore these I thought I had finally found the perfect slipper. These were true to size and very comfortable. After just a few days, something inside the soles started bunching up to the point it felt like there were pencils stuck across the soles under my heels as I walked. I wore them a little longer hoping maybe it would get smashed down after a time, but it only got worse. When I looked up the manufacturers warranty, I found on their website you had to pay to mail the defective slipper to them and enclose $5 to pay for their return shipping of a new pair for you. At $13 for a brand new pair, this just isn't worth it. When I went to throw them away I also noticed the fabric on the bottom close to the soles was starting to wear through.

The slippers are very comfortable, however, one of the flowers came off almost immediately.  I glued it back into place, however, I do not feel that it will hold up during washing.

The slipper is warm and comfortable, but they are already coming apart. I lost a chunk of sole from both shoe.

Love the hoodie but have only had for less than a week and the lettering is coming off.  Not happy.
