5 Sneaker Care Myths That Are Quietly Ruining Your Kicks

Every sneaker owner has a "trick." Toothpaste on the midsole. A spin in the washing machine on the gentle cycle. A magic eraser attacking the toe box. Most of this advice gets passed down like folklore — confidently, constantly, and without much evidence. The trouble is, folklore doesn't know what mesh, foam, and glue are actually made of. We do. After a century and a half of Canadians walking through their front door, we've seen what these "hacks" do to a pair of sneakers six months later. Here are five of the most repeated ones — and what actually works instead.

Myth #1: "Toothpaste whitens soles."

Toothpaste contains mild abrasives designed to polish enamel — not rubber or foam. Rubbed onto a midsole, those same abrasives scratch the surface at a microscopic level, which actually makes soles pick up dirt faster afterward, not slower. Any whitening effect is temporary and often followed by a duller, more porous surface a few wears later.

What actually works: a gel cleaner formulated for rubber and foam breaks down oxidation and grime chemically, without sanding away the surface. Left on for a minute before scrubbing, it lifts yellowing without the collateral damage.

Myth #2: "The washing machine is basically the same as hand-cleaning."

It isn't, and it's one of the fastest ways to shorten a sneaker's life. Machine agitation stresses the glue bonds holding the upper to the sole, spins moisture into the midsole foam, and can warp panels that were never meant to hold water. Sneakers that survive a wash cycle often come out technically clean and structurally worse.

What actually works: hand cleaning with a brush and a sneaker cleaning kit gives you the same result with none of the risk — because you control exactly how much water and pressure touches the shoe.

Myth #3: "Waterproofing spray will change how my sneakers look."

This myth keeps a lot of sneakers unprotected. A quality water repellent spray is designed to sit invisibly on the material — it doesn't add sheen, doesn't darken canvas, and doesn't stiffen mesh. What it does do is give rain, slush, and spills something to bead off of instead of soak into.

Myth #4: "If they don't look dirty, they don't need cleaning."

Salt, oil, and UV exposure work on sneakers long before a stain becomes visible to the eye. By the time yellowing or graying shows up, the damage is already partway done. Sneakers that get a quick wipe-down before they look dirty tend to hold their colour and shape far longer than sneakers cleaned only in emergency mode.

What actually works: keep a pack of shoe wipes by the door for the 30-second habit — wipe after a wet commute, wipe after a scuff, and save the deep clean for once every few weeks instead of once a season.

Myth #5: "Any cleaner will do — it's just soap and water."

Dish soap and multi-surface cleaners are built to cut grease on countertops, not to be gentle on mesh, foam, and adhesive. Used repeatedly, they dry out material and break down glue lines faster than dirt ever would. A cleaner formulated specifically for sneaker materials is pH-balanced to lift dirt without attacking what holds the shoe together — which is why the Sneaker Care collection exists as its own category, not a repackaged household product.

The Real Routine (No Myths Required)

●       Wipe down after wet or dirty wear — don't wait for visible stains

●       Deep clean every 2–4 weeks with a proper sneaker gel and brush

Apply water repellent spray after cleaning, once fully dry

Swap tired laces from the Shoe Laces collection — it's the fastest refresh there is

None of this requires toothpaste, a washing machine, or a magic eraser. Just the right tools, used a little more often.
