Hey everyone, it’s Jake from your go-to nonwoven insole board supplier, and today we’re chatting about something that’s been popping up in my DMs and at industry trade shows more and more: can nonwoven insole board actually work for cycling shoes? Spoiler alert—before we get into the thick of it, if you’re a cyclist or a shoe designer scratching your head over this, stick around. I’ve been selling nonwoven insole boards for over 7 years now, and I’ve tested more prototypes than I can count, so let’s cut the jargon and get real. Nonwoven Insole Board
First, let’s break down what nonwoven insole board even is, for anyone who’s not deep in the material game. It’s not that fancy stuff you see in disposable face masks—wait, okay, some of the same fibers are used, but this is a heavier-duty, precision-engineered version. We make ours from a blend of recycled polyester and polypropylene (no weird chemicals, promise) that’s needle-punched and heat-calendered to create a firm, consistent structure. It’s the stuff that keeps insoles from squishing down after a month of wear, right? You know when you buy a pair of running shoes and the insole feels like a pancake two weeks in? That’s because cheap insoles use flimsy foam or pressed cardboard that breaks fast. Our nonwoven insole board doesn’t do that—it’s got the stiffness of a thin plastic sheet but way more breathability.
Now, why would anyone even consider swapping cycling shoe insoles (which are usually foam, EVA, or carbon fiber) for nonwoven stuff? Let’s start with the biggest pain point for cyclists: foot fatigue. I talked to a pro road cyclist at a race last year who told me his feet would go numb after 2 hours of steady climbing, no matter how many different insoles he tried. The problem with standard cycling insoles is that they trap moisture—sweat builds up, the material gets squishy, and it creates a slippery, uncomfortable gap between your foot and the cleat. Our nonwoven insole board is porous, so it wicks sweat away way better than EVA foam. I tested this myself last spring when I swapped my old road bike insoles for a custom cut of our nonwoven board. After a 3-hour ride, my feet were dry—no that squelchy feeling I usually get, and no numbness. That’s a win right there.
But wait, cyclists need stiffness, right? If your insole is too soft, it wastes power when you push down on the pedals. That’s the whole point of cycling-specific insoles—they’re designed to be rigid so every ounce of your effort goes into turning the crank, not squishing into your shoe. So here’s the million-dollar question: is nonwoven insole board stiff enough for cycling? Let’s get specific. Our nonwoven insole board has a flex modulus (that’s a fancy way of saying how resistant it is to bending) of around 1200 MPa. Compare that to the EVA insoles most recreational cyclists use, which are around 200–500 MPa. Carbon fiber insoles are stiffer, like 5000 MPa, but those cost a fortune and can be too rigid for long rides—they don’t absorb any shock, so your knees and feet take a beating on rough roads.
That sweet spot at 1200 MPa is exactly where it works for cycling. I worked with a small shoe manufacturer last month to test a batch of their entry-level road shoes using our nonwoven insole boards instead of their standard foam ones. The feedback was crazy positive—riders said they got 10% more power transfer on climbs (they actually measured that with power meters, not just guesses) and less foot pain after long rides. The stiffness is consistent too—unlike foam that breaks down over 500 miles, our nonwoven board stays the same for over 2000 miles of wear. That’s a huge cost saver for casual cyclists who don’t want to replace their insoles every few months.
Another big plus: customizability. A lot of cycling shoes are one-size-fits-most, or have insoles that only come in a few standard widths. Our nonwoven insole board is super easy to cut with a regular leather cutter or even a sharp pair of scissors, so shoe makers can produce custom fit insoles without having to invest in expensive molding equipment. I heard from a boutique cycling shoe brand that uses our board to make custom insoles for riders with wide feet—they can cut a custom shape in 5 minutes, and the rider gets a perfect fit that prevents blisters and hot spots. That’s way faster and cheaper than using pre-molded carbon insoles for every custom order.
But hold up, it’s not all sunshine and smooth rides. There are some caveats we have to talk about, because we don’t want to oversell this. First, if you’re a pro racer looking for the absolute stiffest setup possible for sprinting, nonwoven insole board might not be your top pick. Carbon fiber is still better for that extreme stiffness, especially for short, high-power efforts. We actually get a lot of pro teams testing our board for training shoes, though—most pros do 10+ hour training rides a week, and the breathability and fatigue resistance of nonwoven is way better for long days in the saddle.
Another thing: waterproofing. Our standard nonwoven insole board absorbs some moisture, which is great for sweat, but not so great if you’re riding in heavy rain or through puddles. Wait, but here’s the fix—we can coat the board with a thin, water-repellent polymer that keeps the fabric dry while still letting sweat escape (it’s called moisture vapor transmission, and it’s a thing—you can have a material that blocks liquid water but lets water vapor pass through). We tested this coated version last fall with a group of mountain bikers, and they said their feet stayed dry even after 4 hours of riding through mud and puddles. That fixes the main complaint people have about nonwoven materials being too absorbent.
Also, let’s talk about durability. I mentioned earlier that it lasts 2000 miles, but if you’re a mountain biker who’s dropping off rocks and scraping your shoes on trail obstacles, you might need to add a thin layer of protective coating to the bottom of the insole. It’s not that the nonwoven breaks, it’s that it can get scuffed up, and scuffs don’t affect performance at all—they just look weird. So we usually suggest a thin, clear polyurethane coating for mountain bike insoles to keep them looking new longer, and it doesn’t add any extra bulk that would throw off your fit.
Now, let’s talk real-world examples because numbers are great, but actual riders’ experiences matter more. Last year, we supplied a batch of nonwoven insole boards to a cycling gear startup that makes affordable commuter shoes. Their old shoes used foam insoles that got smelly after 2 weeks (thanks to trapped sweat and bacteria). The commuter shoe market is huge—tons of people ride to work, and they want shoes that are comfortable, don’t smell, and last. After switching to our nonwoven board, they saw a 30% jump in repeat customers because the insoles don’t hold odor. Why? Because nonwoven materials don’t trap bacteria the way foam does—you can even throw the insoles in the washing machine, and they come out looking and working just like new. I’ve tested that myself—washed my prototype insoles after a long muddy ride, and they dried completely in 4 hours on my bike, no shrinkage or stiffness loss.
Another test I did personally: I’m a recreational cyclist, I do about 100 miles a week, mostly on mixed road and gravel. I used to use $50 carbon insoles, but they got so hot in summer that my feet would sweat through my socks, and the stiffness made my knees ache after long gravel rides. I switched to our nonwoven insole board cut to fit my shoes, and the difference was night and day. In summer, my feet stay dry—no more sweaty socks at the end of my commute. On gravel rides, the flexibility is just enough to absorb the small bumps, so my knees don’t hurt, and I still get plenty of power when I’m climbing hills. The best part? A full set of our custom cut insoles costs $8, compared to $50 for carbon or $20 for high-end foam. That’s a no-brainer for anyone on a budget.
Wait, but let’s address the elephant in the room: why haven’t more cycling shoe brands jumped on this? It comes down to two things: familiarity and certification. A lot of big brands have been using foam or carbon insoles for decades, and switching to a new material requires retooling their production lines, testing for safety, and getting rider feedback. Also, some brands are worried that nonwoven is “too industrial” for high-end performance shoes. But we’re seeing that change—smaller, innovative brands are testing nonwoven insole board, and even some mid-tier brands are offering it as an upgrade option for their entry-level models. The key is that nonwoven isn’t trying to replace carbon—it’s filling a gap between cheap foam and expensive carbon, giving riders a middle ground that’s comfortable, durable, and affordable.
Let’s also talk about sustainability, because that’s a huge topic right now in the cycling industry. A lot of cyclists care about reducing their environmental footprint, and our nonwoven insole board is made from 100% recycled polyester and polypropylene. Each set of insoles diverts about 2 plastic water bottles from landfills. Compare that to carbon insoles, which are plastic-based and can’t be recycled easily—most end up in landfills when they wear out. EVA foam insoles aren’t much better, they take years to break down and often have harmful chemicals added. So if you’re a cyclist who wants to ride green, nonwoven insole board is a way better choice.
Now, let’s wrap this up with a clear takeaway. If you’re a casual or recreational cyclist, or a commuter who wants affordable, comfortable, long-lasting insoles that don’t smell or trap sweat: yes, nonwoven insole board works perfectly. If you’re a pro racer chasing every last bit of stiffness for sprinting: it’s not the top choice, but it’s great for training rides. If you’re a shoe manufacturer looking to cut costs, offer custom fits, or make more sustainable shoes: this is a material you should definitely test.
TPU Sole I’ve been in the nonwoven game long enough to know that new materials take time to catch on, but the feedback we’ve gotten from cyclists and shoe makers has been really encouraging. We’re currently working on a new, lightweight version of our nonwoven insole board for road racing that’s got a bit higher flex modulus, so it’s stiffer than our standard version but still breathable and affordable. If you’re a rider who wants to test some samples, or a shoe brand that wants to work with us to design custom insoles, hit me up—we’re here to help. We don’t do pushy sales stuff, we just make a material that works, and we want to get it in as many cycling shoes as possible.
