Waterproof Trainers vs Gore-Tex: What's the Difference?

If you've ever bought waterproof trainers and still finished a run with damp feet, you're not alone. The label tells you the shoe is built to keep water out, but it doesn't tell you how well it breathes, how long the protection lasts, or how quickly it dries once water does get in. Understanding the difference between a coated trainer and a membrane shoe like Gore-Tex takes the guesswork out of buying for UK conditions.

Waterproof is a broad label. It covers any trainer built to keep water out, but the method varies a lot between brands. Some waterproof trainers use a durable water repellent (DWR) coating sprayed onto the mesh upper. This coating causes rain to bead up and roll off rather than soak in. It works well in light drizzle but wears off with washing and heavy use, usually within a season of regular runs.

Other shoes go further and build in a waterproof membrane, a thin, laminated layer sandwiched between the outer mesh and the inner lining. This membrane physically blocks water molecules from passing through, so it keeps working long after a DWR coating has faded. Gore-Tex is the most recognised membrane brand, but it isn't the only one. eVent and Salomon's own ClimaSalomon membrane both do a similar job. Some brands sell simpler "WP" (waterproof) versions of a shoe that rely on a treated, sealed upper rather than a named membrane technology.

Gore-Tex is a specific membrane technology, not a generic word for "waterproof." The membrane contains over 9 billion microscopic pores per square inch, each one roughly 20,000 times smaller than a water droplet but around 700 times larger than a water vapour molecule. Rain and puddle splashes can't squeeze through, while sweat vapour escapes easily. Think of it like a fence built for footballs, not marbles: rain bounces off, while sweat vapour slips through.

That combination, blocking liquid water while letting vapour out, is what separates Gore-Tex from a basic waterproof coating. A shoe with only a DWR treatment or a cheaper waterproof film can keep rain out just as well in the short term, but it often traps heat and moisture inside instead, leaving your feet clammy after a hard effort.

Here's how the two typically compare in a running shoe:

This is the question worth answering before you spend extra on a membrane shoe. Waterproof trainers and Gore-Tex running shoes earn their keep in specific conditions, not every run.

• Run trails through mud, long wet grass, or shallow stream crossings regularly
• Commute by foot or run through commuter traffic in persistent UK rain
• Train through a full winter and want one shoe that copes with slush, sleet, and standing water
• Run in temperatures close to freezing, where dry feet stay noticeably warmer than wet ones

• Mostly run on dry roads or a treadmill
• Run in warm or humid weather, where the reduced airflow can make feet sweatier, not drier
• Regularly cross streams or run through puddles deep enough to go over the ankle collar, since water gets trapped inside once it's in
• Want the fastest possible drying time after a wet session

This is one of the questions among trail runners, and the honest answer is: it depends on your terrain, not your ambition. On UK fells, moorland, and forest trails through autumn and winter, a Gore-Tex trail shoe earns its price by keeping feet dry through boggy sections and long wet grass.

Fell and mountain runners covering exposed, cold terrain benefit most, since dry feet help regulate body temperature when the wind picks up.

Ultra-trail and adventure runners covering long days out should weigh up dry-out time too. If a route includes river crossings or sustained deep puddles, a non-waterproof shoe that drains and dries quickly can actually keep feet more comfortable over many hours than a Gore-Tex shoe holding onto trapped water.

Yes, and this catches a lot of first-time buyers out. A Gore-Tex running shoe is not a wellington boot. Rain and puddle splashes get blocked by the membrane, but water can still enter over the low-cut ankle collar during deep puddles, stream crossings, or standing in wet grass for long periods.

Once inside, that water struggles to escape, because the same membrane keeping rain out also keeps trapped moisture in. For most road and light-trail runners, this rarely matters. For anyone tackling deep water crossings, a higher gaiter or a simple non-membrane shoe that drains and dries fast can be the better call.

Not every runner needs the same shoe, so here's how the choice tends to play out by running style:

Waterproofing performance drops with poor care, whatever type your trainer uses. For a full step-by-step routine, including cleaning, drying, and reproofing, see our complete guide to Gore-Tex trainers. The short version: rinse off mud promptly, air dry away from radiators, and reproof the outer DWR coating every few months so water keeps beading off the surface.

Muddy trails and winter roads favour a membrane shoe. Dry roads and gym sessions don't need one at all.

Cold, wet months make the breathability and warmth of Gore-Tex worthwhile. Warmer months often suit a lighter, non-waterproof mesh shoe instead.

Short, sharp sessions in the rain are fine in either option. Long trail days or ultras benefit from considering dry-out time as much as water resistance.

A Gore-Tex version typically costs more than the standard shoe. Decide if the extra dryness and durability justify the price for how often you'll actually use it.

If deep water crossings or fast drying matter more to you than total waterproofing, a non-membrane trail shoe with good drainage might suit you better than either option.

Gore-Tex is a specific waterproof membrane, not a general term for any waterproof trainer. It blocks rain while letting sweat vapour escape, which sets it apart from basic DWR coatings that fade over time. Waterproof trainers suit UK winters, muddy trails, and wet commutes, while dry roads and warm weather rarely need one.

Once water gets in over the collar, both membrane and non-membrane shoes hold onto it, so match your choice to your actual conditions rather than the shoe with the most technical-sounding label.
