Shoes color change

Is that suede or smooth leather?  
Suede is absorbent and notoriously temperamental in water (see Seinfeld).
Another complication of Winter wetness is salt.

You could try dunking or dyeing both shoes, overwhelming the spots.
Or just wear them as is and trust to eventual weathering to bring them back together.

The cause my be related to the length of time in contact with water.
- The best solution might be dye of at least a good suede polish

The waterproofing or stain resisting sprays you get would, in all probability, have changed the colour of the suede anyway.  It will always tell you on the spray can or bottle to test on an inconspicuous area first because they take no responsibility for all the different types of leather you can get.  Water repellent liquids need to wet the surface and allow the waterproofing substance to soak into the outside layer.  They are usually in a fast drying liquid like alcohol or other spirit so that the wetting is minimised, but any type of wetting on suede can affect the colour and texture.

A leather hide from a cow is almost always split because it is too thick for any practical uses.  The upper layer with the grain is used for furniture, jackets, and traditional leather shoes.  It sometimes has the grain smoothed off (nubuck), sometimes has an artificial coating applied, and is sometimes mechanically and artificially re-grained.

The upper side of the bottom split is used for proper suede, hence the fuzzy texture.  It doesn't have as many natural oils as the "grain split", but from a good piece of leather it is still nice and dense but supple.

Cheaper cuts of leather, such as a third layer from the bottom or middle splits from old cows/bulls, is sometimes wrongly described as suede, and sometimes has an artificial grain embossed into it so that it can be wrongly advertised as "grain leather".  The hide is more fibrous and less pliant the further down the skin you get, and cheap quality "suede" is just the crappy bottom layer buffed with wire brushes or sanded coarsely to resemble proper suede.

There are all kinds of British Standards and European Directives that specify what can be called real leather and carry that familiar "Real Leather" cow-hide shaped tag.

Suede was never intended to be worn in wet environments.  You mostly find suede used in "Desert Boots" or variants of that style.  You can get small brass wire brushes to buff suede and make it fuzzy again, but if the discolouration is caused by the dye in the leather running or by some other coloured liquid, then you will probably never be able to brush the suede deeply enough to remove it without damaging it.

You will be aware of the Sale of Goods Act 1979 in the UK:

You may be able to get a full refund for the boots if you can demonstrate that they were advertised or described as being suitable for wet wintry UK weather, but with no mention of the fact that suede isn't waterproof and will stain.  That would be the "as described" part of the act.

If you could prove that the dye in the suede was of poor quality and separated more than it should have, then that would be the "satisfactory quality" clause, but that would be impossible to prove without paying lots of money to http://www.blcleathertech.com/testing-services or other independent company.

You could argue the point that "everyday use" in the UK can involve experiencing all four seasons, and therefore maintain that the boots were "not fit for purpose", but it all depends what care and usage instructions came with the boots.

If the suede boots were advertised in the UK along the lines of "keep your feet dry and warm this Winter", then you would have been perfectly entitled to claim a full refund in terms of the Sale of Goods Act on reading an instruction leaflet that said "not intended for wet weather" or "may discolour if boots get wet".  If, however, you ignored any such instructions on instruction leaflets or tags, did not treat them with the recommended water repellent, and wore them in wet weather, then your claim is really invalidated.

If no instructions came with the boots in any form, and you therefore were unaware of the fact that the suede boots might stain after getting wet, then I would say you could demand a refund in terms of the Sale of Goods Act on the basis that there was no inferred restrictions on use other than as "everyday footwear".

You should be aware that the Sale of Goods Act covers goods bought over the Internet as long as they are not sold as an auction, eg. eBay even if it was a "buy it now" sale.  So if you bought the goods via the Next website you can invoke the clauses of this act.

Those boots will not have been cheap.  Nothing from Next is cheap, but when I say "cheap" I don't necessarily use that to describe quality.  Marks & Spencer, once an outlet that sold only good quality clothing, now has most of its garments made where labour is much cheaper and quality has suffered, but the prices haven't dropped.  I'm not criticising your choice of shop, because most fashion chains charge far too much for what the goods actually are these days.  I know because I work in that industry.

I mention this because I do not think you should even attempt to remove the staining before you at least try for a refund or exchange.  One of the exemptions that a retailer will use to invalidate a claim for refund is if you have tried to fix the problem yourself.  Those boots are too pricey to take a chance with.  If they were just a cheap pair of two lace-hole "dessy boots" with thin foam rubber soles and little in the way of lining, then by all means get a wire brush on a power drill and get stuck in, but don't try that with your boots.

Aha!  Sorry viki2000, when you said "I bought few months ago next pair of shoes" I thought you were referring to the retail fashion chain called Next which is big in the UK and I believe also in Europe.  Sorry about that, I assumed you were based in the UK.

Germany will have very similar Trading Standards and Consumer Protection laws, and there will no doubt be equivalent government departments who can advise consumers about their rights.

I see that there is a small icon next to the Borelli logo that tells you the boots comply with the laws regarding what can be sold as "Real Leather".  Again, there will be equivalent European or German laws concerning what constitutes real leather, and it is probably exactly the same as the UK "British Standards" (BSI).

Unfortunately I don't speak German, so I would find it hard to look at the Deichmann website's "Terms and Conditions".  I could probably copy and paste into Google Translate, but often it changes the meanings of sentences, and I am sure some of the sentences will be very long.

We often hear and read the expression "Terms and Conditions Apply", in adverts, and they then say (quite often very quickly so we don't quite hear it) "Statutory Rights Unaffected".  What this means is that, although there may be conditions set by the shop regarding what space of time you may return the goors, or that they may charge a handling fee, etc, etc, BUT IF you are asking for a refund or exchange because of your "statutory rights" (or rights as a consumer), then they can override their terms and conditions.  For example, if they give a 14 day exchange clause, but the shoes tear after wearing them for normal activities for 21 days, you can still claim a refund because of faulty materials or workmanship, or any other clause of the consumer laws in Germany.

In such cases you will not always need a receipt, as long as you have some proof that the boots were bought from that retailer.  Occasionally claims about faulty materials or workmanship, or similar issues, are referred to the actual manufacturer.  Unless you are told otherwise, your first complaint should always be with the shop that sold the goods.

You can usually also claim back reasonable travelling costs to return the faulty or misadvertised goods, and also any postal costs for returning them.  Just be sure to post the boots on a service where the shop's returns department signs for them if you have to.  Most often companies first have to issue you with a unique return number before you send the goods back.  Be sure to complete any documentation of web forms completely.  In most cases they will also tell you that they will inspect the goods and if they do not find them faulty or defective, then they will charge you an administrative fee and will not reimburse postal costs.

I will load the web page into Google Chrome when I get home in the morning, because that will try and translate the contents of the page.  I am at work right now.  I will look for any advertising expressions in the description of the boots that implies they are ideal for outdoor use in Winter, or in any weather, but do not mention that they are not waterproof.

I would avoid applying any kind of wax, polish, or other similar stuff onto suede.  It will ruin them and completely invalidate any claim that you might have against the retailer.  It might be tempting to think you could make them look like a normal shiny pair of soft shoes if you polish and buff them up, but suede is fuzzy and you would have to apply many coats and rub it in for ages to get anything like the appearance of normal leather shoes, and the style will not match the polished appearance.

You might note that most animals which produce leather have coats that are naturally uneven. To produce suede with an even color requires that it goes through a dyeing process to produce that. Unfortunately, when suede comes in contact with moisture it's going to change color, and do so in an uneven manner. You might try having the boots re-dyed but that may cost more to have done properly than buying a new pair. For years I've been wearing boat shoes that originally come in blue suede and they have always changed color in a pretty short period of time. In fact, one of the pairs I would now classify as being green and not blue. Fortunately, boat shoes are kind of meant to look a little ratty. In truth, the rattier they look the better people think you know how to sail. I'm not sure what the intended purpose of your boots are, but maybe they're intended to look "used" as well. There doesn't appear to be an easy solution to your situation, if one exists at all.
