Winter running is usually a mess of wet socks and slipping on black ice. Most people just buy a pair of Gore-Tex sneakers and hope for the best. But then there's the La Sportiva Blizzard GTX. This isn't really a sneaker. It’s more like a technical mountain tool that happens to have laces. If you’re looking for a soft, pillowy ride to jog around a cleared suburban sidewalk, honestly, look elsewhere. This shoe is built for the kind of conditions that make most sane people stay inside with a hot coffee.
I've seen runners try to use these on dry pavement. Don't do that. It feels like wearing soccer cleats on a basketball court. The Blizzard GTX is a hyper-specific solution to a very cold, very slippery problem.
The Integrated Gaiter is the Real Hero
Most "winter" shoes stop at the ankle. Snow gets in. Your feet get wet from the top down. It's annoying. La Sportiva fixed this by sewing a Sock-Shield Gaiter directly into the shoe. It’s water-repellent and wraps high around the ankle. Basically, it keeps out the slush, the scree, and that annoying frozen crust that usually scrapes your shins raw.
The Gore-Tex Extended Comfort liner handles the internal moisture. It’s a breathable membrane, but let’s be real: if you’re working hard in 30-degree weather, your feet are going to sweat a little. The magic here is that the moisture moves out while the freezing slush stays out. You don't get that "heavy sponge" feeling halfway through a ten-mile loop.
The lace pocket is another small but vital touch. You tuck the laces into the gaiter so they don't snag on frozen branches or get coated in ice. If your laces freeze into a solid block of ice, you aren't getting those shoes off without a hairdryer. The Blizzard avoids that nonsense entirely.
Tungsten Spikes: Grip That Actually Bites
Let's talk about the outsole because that’s where the La Sportiva Blizzard GTX separates itself from the "trail runners" you find at a big-box store. It uses the FriXion Blue compound. In La Sportiva’s world, "Blue" means high durability and decent grip. But the secret sauce is the integrated tungsten alloy spikes.

These aren't those cheap slip-on Yaktrax that snap after three runs. These are molded into the lugs.
- They bite into blue ice.
- They provide traction on frozen mud that would send you face-first into a tree.
- They give you the confidence to actually run, not just "shuffle-walk," when the trail turns into a skating rink.
It uses 7mm lugs. That’s deep. Most trail shoes hover around 4mm or 5mm. That extra depth is what lets the shoe find purchase in soft powder before the spikes hit the hard stuff underneath. It’s a tiered traction system. It works. It’s also loud as hell on pavement. You’ll sound like a tap dancer if you have to cross a road.
Stiff, Responsive, and Not Very Forgiving
The midsole is injected MEMlex EVA. It’s firm. If you’re used to the "max cushion" trend of Hoka or New Balance, the Blizzard is going to feel like a board at first. But there’s a reason for the stiffness. When you’re pushing off uneven, frozen ground, you need a stable platform. A mushy shoe on ice is a recipe for a rolled ankle.
The 6mm drop is the sweet spot. It’s enough to save your calves on steep climbs but low enough that you still feel connected to the ground. You aren't "floating" over the trail; you're attacking it.
A Quick Reality Check on Sizing
La Sportiva runs small. Like, "did they use a child's foot for this template?" small. Most runners find they need to go up at least a half size, if not a full European size, to accommodate thicker winter socks. If your toes are cramped, they’re going to get cold. Blood flow is the only thing keeping your feet from turning into popsicles, so don't choke them out with a tight fit.

The toe box is also notoriously narrow. It’s a "performance fit." It’s meant to be precise so you don't slide around inside the shoe when you're side-hilling on a 30-degree slope. If you have wide feet, you might struggle with the Blizzard. It’s a mountain shoe, not a lounge slipper.
Where It Fails (Because Nothing Is Perfect)
The price is the first hurdle. It's expensive. You’re paying for the specialized construction and the Gore-Tex license.
Another downside? Versatility. You cannot wear the La Sportiva Blizzard GTX in the spring. Once the ice melts, those tungsten spikes will wear down on rocks and pavement, and they’ll feel incredibly uncomfortable. This is a seasonal tool. It sits in your closet for eight months of the year. But for those four months of winter? It’s the only thing you’ll want to wear.
Also, the weight. At roughly 370 grams (13 ounces), it’s heavy. You feel that weight at the end of a long run. But you have to weigh that against the safety of not slipping and the comfort of staying dry. Most people find the trade-off worth it.
Technical Specs You Should Know
The construction is beefy. The upper is made of abrasion-resistant, water-repellent mesh. It’s tough. You can kick rocks and frozen branches all day, and the material won't shred.

- Weight: ~370g (half pair)
- Drop: 6mm

It’s a lot of shoe.
Final Insights for the Winter Runner
If you're serious about mountain running in the winter, the La Sportiva Blizzard GTX is basically the gold standard. It’s built for the Dolomites and it shows. It handles technical terrain better than almost anything else on the market.
Don't buy these if you only run on plowed roads. You’ll hate them. The spikes will vibrate through your feet and the gaiter will feel like overkill. But if your local trails turn into a treacherous mix of ice, slush, and deep snow, these are a literal lifesaver.
Actionable Next Steps:
- Check your local terrain: If you encounter "black ice" or packed snow more than three times a week, the spikes are worth it. If not, look at the La Sportiva Cyklon Cross GTX—it’s similar but without the permanent spikes.
- Size up: Order at least a half-size larger than your standard running shoe. Bring your thickest wool socks to the fitting.
- Inspect the spikes: After every season, check the tungsten tips. They are durable, but they aren't invincible. If you've been running on granite, they might need a look.
- Store them dry: Never put them on a high-heat radiator. The Gore-Tex membrane and the glues can degrade. Air dry them with the insoles removed.
