BEWARE---  Dyes soles of feet black!
593789
I love the comfort of these shoes, but will never by YellowBox again due to the dyes that they use turn the soles of your feet black!  It would be forgivable if they only caused this the first few times they are worn, but I have had these for about 2 months and when I went for a pedicure, the girl told me that my soles of my feet were dyed black. Really upsetting!!! It is something that Yellow Box has no solution for either.  Which I find rather odd, because when I wrote in to their website, they didn't offer any help to remedy the problem.  So, I have 3 pair that I will never wear.  :(

This product stripped the color out of my shoes. That's a pair of $90 shoes completely ruined now. You can clearly see in the picture, the darker parts are what shade my shoes used to be before using this product to clean them.

Of course I love my Uggs! I have two other pair. The soles of my other boots are a little more involved so my two other brown pair have a little more arch support. My new black ones have a little less arch support, but I've been walking in them a lot and have no issues. They are like wearing slippers all day, they're great!  My one problem is these boots are black and everyday for the week I've owned them I've had to try to scrub the black off of my feet from the dye. (and I can't get it all off)  I'm not sure why you would have to dye the inside of this boot at least not the working part. My heels are dark black and pretty much stained. I'm not sure if everyone else wears their Uggs like I do. I wear them like slippers with no socks, so this is a problem for me. Please Uggs boot makers leave the inside soles of your boots a natural color. : /

the bottom fur comes off in a week, then all the black color stains your bottom of the feet blackened. Do not buy!!! this is not Ugg!! the fur is FAKE.

I love love love the feel and fit of these slippers....however I got the black with black fur and the bottom of my feet turned black from the dye after wearing them for just one day. I did not get them wet either. I can not even get it all off with soap and water!
So sad because I love how they feel and they keep my feet warm. Just don't like the idea of my feet turning black.
Going to exchange for a natural color fur inside.........

I wish I had read some reviews on this product.  First time I wore this apron the black color rubbed off all over my white jeans and tee shirt.  Usually polyester is colored before it is spun into thread.  It does not take dye well and yet this manufacturer is selling white aprons dyed after manufacture.  I bought 2 of these and will burn them if I can't return them.

The shoe is very comfortable but the dye started fading and is continuing to get worse. I keep a good coat of polish on them but it doesn't help. Never had a shoe loose its dye so quickly. Won't ever buy another Ecco shoe.

The fit was fabulous, HOWEVER... I was outside washing off my deck for about an hour.  The flip flops became wet and the dye from the fabric under the rhinestone area stained my skin HORRIBLY!!!
 It literally too over a week after trying to scrub it away daily, to fade!  For that reason it got 2 stars.  I will not ever reorder another pair like this.

I ordered the black with red diamonds. The red dye is not color fast. After required gentle laundry, the red dye bleeds on to all other clothing it touches. Will never buy again.  Red dye will not come out of contaminated clothes.

I've worn them 4 times, and the color transfers to my feet every time. I tried spraying them with waterproofer after the first 2 times but I didn't help. Very annoying. Will not wear them again.

Horrible. The toe looks ridiculous. Based on the product picture, you expect a nice fade from black to tan, however this is not the case. When I opened the box, I found these boots look like they have been dipped in black dye. I showed them to a couple people before returning and they both thought the boots looked hideous. The black dye also is extremely fragile and will flake off easily. If you so much as graze something hard, you can expect the black toe to chip away. Don't buy!

I am beyond LIVID... I just received these last week... I wiped off my new Tesla Model S and threw the rag on the back seat... I took it out about half hour later when I got home and black dye has STAINED MY LIGHT GREY LEATHER?!?

If you look at the pictures, it shows the rags wiping off leather and a light colored convertible/rag top... NEVER.  Frankly, I am on the verge of contacting a lawyer because I am LIVID.  How are you advertising these as detailing clothes as they stain light colored interiors... I used ONLY a little water on them (no chemicals, soaps, etc.)... seriously, heartbroken right now.  I have taken photos of the Amazon description and pictures to show that they appear to be used for this purpose and nowhere do they say their dye will leak onto everything?!?

This product ruined my shoes. My shoes were blue/grey and after using this product they are now dark blue. I used this product on very expensive shoes and it completely  changed the color. Do not use this product on anything but black shoes.

The black clogged up, other colors worked though!

I am having the same issue with this shoe as some other customers--that of the cheap metal button leaving a "tattooed" rust stain on my foot, each and every time I wear them. This has never happened to me with any shoe, let alone a Birkenstock--a company known for its quality and craftsmanship for over 200 years. I have had the Gizeh in Gold Stardust for 2 weeks, and basically have a permanent, circular rust/discoloration stain on my foot now, because I have been wearing these (otherwise perfect) shoes every other day. (FYI, I am a true 6.5-7 and wear a 36M i.e. a "US 5", that's how large these run. This M is also much narrower than previous M widths in my other Birks.) The stain won't even come off in the shower. My nail salon technician saw it, thought it was awful and also couldn't believe it, coming from a Birkenstock. Absolutely unacceptable for this brand and price! I am also concerned about continuing to wear this shoe due to the safety of this mark/metallic rust residue, as it appears that they have used brass as the metal (brass is very cheap, compared to stainless steel), and brass leaches nickel, tin and cadmium (amongst other metals) into the skin and thus the body (what goes on the skin goes in the body), all of which are heavy metals related to numerous health issues. Pretty upsetting. (God only knows what's in the new, hard plastic toe divider.) Listen to your longtime, devoted customers and please fix this, Birkenstock! Rust stained feet from a cheap brass button? You are losing fans left and right. So disappointing.

Sandals look great on your feet but, be prepared to scrub your feet after wearing these - the ink comes off and the bottom of your feet get very black.

The strap bleed colour and stain your feet when its wet. Use in dry areas only! I had a small blister on both feet due to abrasion from the straps. Do not walk more than a mile on these!
