Shoe problem fixer

Tell it what your shoes are made of and what has gone wrong, and you get the fix step by step, what to avoid and what you need, from the makers’ own care guides. The short version: salt lines lift with a gentle dab and slow drying, squeaks are usually an insole rubbing (powder under it), and smelly shoes need a day off to dry between wears.

What’s wrong with your shoes?

What are they made of?

Suede is napped and velvety; nubuck is finer, like peach skin. Rubber or EVA means wellies, clogs and slides.

Suede

  2. SUEDE
  3. NUBK
  4. CNVS
  5. KNIT
  6. PTNT
  7. RBBR

Steps

  1. Let the boots dry completely at room temperature first. Dr. Martens says to let suede dry naturally.
  2. Brush the dried salt out of the nap. LOWA recommends a combination brush with plastic and brass bristles for suede.
  3. Rub what is left with a suede eraser.
  4. Still white? Blundstone’s method: dip the corner of a cloth in white vinegar, dab the mark without soaking the suede, and let it dry.
  5. When dry, brush the nap in one direction and spray a suede protector. Blundstone says its spray guards against salt stains as well as water.

Avoid

  • Getting suede too wet (Dr. Martens). Dab with the corner of a cloth, never scrub with a wet one.
  • Heat to speed up drying: radiators, hair dryers, a fire or a hot car. Red Wing says intense heat makes leather crack, stiffen and lose its oils.
  • Using the brass brush or eraser on smooth leather: LOWA says they are for suede only.

You need

  • Suede brush (brass and plastic bristles)
  • Suede eraser
  • White vinegar
  • A clean cloth
  • Suede protector spray

How the fixer works

There are seven materials and ten problems, so seventy answers, and each is written for that pair. Suede gets a brush and an eraser, never polish; knit gets cool water rather than a hot wash; patent gets a damp cloth and a buff. Six of the seventy have no fix because there is no problem to fix. Patent leather and rubber don’t take water marks, canvas, knit and moulded rubber don’t hold creases the way leather does, and clogs have no laces to come undone. The fixer says so rather than inventing a remedy.

Each step names the maker whose care guide it comes from, among them Red Wing, Dr. Martens, LOWA, Blundstone, Nike, Allbirds and Crocs, so you can check the original. Where makers disagree, the answer says that too. Before you use any cleaner, try it on a hidden spot such as the inside of the heel.

How to fix squeaky shoes

Nike puts squeaks down to three main culprits: water, newness and friction. Where the noise comes from tells you which:

  • Under your foot, even on carpet: the insole is rubbing. Lift it out and dust baby powder or talc underneath; Nike and Skechers both suggest it.
  • Only on smooth floors: usually new rubber soles. Skechers suggests walking on a dry, rough surface to break them in.
  • After rain: moisture trapped inside. Nike’s advice is newspaper inside and about 12 hours somewhere ventilated.
  • A click from the heel or arch: parts of the shoe working loose. London shoemakers Carreducker traced one such squeak to a shifting shank, the stiffener under the arch. That is a repair job.

The squeaky shoes page walks you through finding the spot, one question at a time.

How to get salt stains out of boots

The white tide marks are dried de-icing salt. Iowa State University Extension notes that most de-icers sold are chloride salts: sodium, calcium, potassium or magnesium chloride. Makers’ methods depend on the leather:

  • Smooth leather: LOWA says water with a light soapy solution is usually enough. For a stubborn line, Tory Burch’s care tip is equal parts white vinegar and water, dabbed on and wiped off with clean water.
  • Suede: let it dry, brush, use a suede eraser, and only then, as Blundstone suggests, dab with the corner of a cloth dipped in white vinegar, without soaking the suede.
  • Nubuck: an eraser bar, wetted and repeated if the mark persists, then a brush to raise the nap (Red Wing).

We looked for a maker or a laboratory that explains why vinegar shifts the white lines and found none, so we won’t invent a chemistry lesson. What every maker agrees on is the drying: at room temperature, never on a radiator. The salt stains guide has a printable step card for each material and the prevention routine for the rest of the winter.

Why shoes smell

The NHS says smelly feet are often caused by a build-up of sweat and bacteria, and the Royal College of Podiatry notes that feet have about 250,000 sweat glands. The shoes soak it all up. The NHS advice: wash your feet at least once a day, don’t wear the same socks or shoes two days in a row, and let shoes dry out before wearing them again. The smelly shoes planner turns that into a two-week rotation for your own pairs, with wash days for the ones that can be washed.

Three things makers warn against

  1. Heat. Red Wing says intense heat dries leather out too fast, so it cracks and stiffens; Hanwag adds that heat shrinks leather and can affect the bonding; Crocs says extreme heat can make its shoes shrink or warp. That rules out radiators, hair dryers, fireplaces and the parcel shelf of a hot car.
  2. The washing machine, for leather. LOWA says you should never machine-wash leather or synthetic shoes, and Hanwag says the same of hiking boots. Nike doesn’t recommend the machine for its shoes either. Allbirds is the exception: most of its shoes can go in on a gentle, cold cycle.
  3. An iron on creases. Nike warns that a hot iron directly on a shoe can damage it beyond repair. Shoe trees prevent creases; nothing reliably irons them out.

When it’s a job for a shoe repairer

Powder and patience fix a lot, but not everything. A heel that moves, a sole that has started to come away, a click from the arch that won’t go away, or leather shoes that need more stretch than a few evenings in thick socks can give: these need someone with a workbench. A repairer can also tell you whether a pair is worth saving. For fit problems, start with the foot measuring guide and the lacing diagrams; for sizes in EU, UK and US numbers, our sister site Atlas Stitch has a shoe size converter.

Questions

Is white vinegar safe on leather boots?

Makers that suggest it use it gently. Tory Burch’s tip is equal parts white vinegar and water dabbed on leather, then wiped with a cloth dampened in clean water; Blundstone dabs suede with the corner of a cloth and warns against soaking it. Try it on a hidden spot first, let the boots dry at room temperature, and put back wax or protector afterwards.

Can I put my trainers in the washing machine?

Only if the maker says so. Nike does not recommend it for its shoes, and LOWA says never to machine-wash leather or synthetic shoes. Allbirds says most of its shoes are fine on a gentle, cold cycle in a delicates bag, with no tumble dryer.

Why do my new shoes squeak?

Usually the new rubber soles on smooth or polished floors. Nike lists newness as one of the three main causes, and Skechers suggests walking on a dry, rough surface to break the outsole in. If the squeak is under your foot instead, powder under the insole.

What is the fastest safe way to dry wet shoes?

There isn’t a fast one that makers recommend. Take the insoles out, stuff the shoes with newspaper and leave them somewhere ventilated; Nike says about 12 hours, and LOWA says to change the paper daily until they are dry. Heat from radiators or hair dryers cracks leather and can warp foam.

Is this medical advice?

No. It is general information about looking after shoes. For foot pain, a smell or sweating that doesn’t improve with the NHS self-help steps, or any foot problem that hasn’t cleared up within three weeks, see a GP or a registered podiatrist.
