“Change How You Walk Forever with KEEN WK400: The Waterproof Version

Waterproof, propelling, eco-friendly, versatile, durable

Sometimes, life is a stroll, not a mad dash. The journey needs to be savored, every step of it, whether you're meandering through a local farmers market, trekking down a rain-slicked cobblestone alley, or marching through an amusement park with the determination of a seasoned explorer. But a stroll isn't as simple as it sounds. Oh no. Like any worthy endeavor, it requires the right equipment. And when I say “right equipment,” I'm not talking about a Swiss Army knife or a portable espresso maker; I'm talking about the unsung heroes that bear the brunt of your wanderlust: your shoes.

Enter KEEN's WK400 Waterproof Walking Shoe, a marvel of modern footwear. It's a shoe designed not just to get you from point A to B, but to make that journey feel like a natural extension of yourself. Like a set of wheels for your feet. This isn't just any ordinary walking shoe, you see; it's like the Swiss watch of pedestrian propulsion.

The first thing that grabbed me about the WK400 is the KEEN.CURVE technology built into the midsole. It's designed specifically to keep you rolling forward, with a constant curve from heel to toe that doesn't just support your feet but propels you. You're not just walking; you're gliding with purpose. This technology was crafted with the understanding that walking is fundamentally different from running or standing. It's a distinction that few brands have made, and it's exactly what sets KEEN apart.

But the piece de resistance? The waterproof factor. Oregon weather isn't for the faint-hearted. It's a land where rain is as common as artisanal coffee shops. And KEEN gets it. The WK400 is armed with KEEN.DRY, a waterproof yet breathable membrane that allows you to saunter through a downpour as casually as you would through a sun shower. It's a marriage of practicality and technology, fused together with an eye for detail that makes this shoe ideal for any condition.

Construction-wise, the shoe impresses as well. A high-traction rubber compound outsole with multi-directional lugs ensures that you're well-grounded, whether you're scaling a slippery slope or traipsing across uneven terrain. And let's not forget about the PFAS-free water-repellent coating and the Eco Anti-Odor properties—conscious additions that make this a shoe for the modern, eco-aware wanderer.

Then there's the comfort aspect. The breathable mesh upper, coupled with TPU overlays, provides durable yet lightweight support. A full-length nylon plate adds stability, and the removable PU insole ensures long-lasting comfort. This is a shoe that you can wear all day, one that evolves with your foot's contours to provide a secure fit. It's got the soul of an adventurer and the brain of an engineer.

At $131.25, the WK400 isn't exactly a throwaway purchase. But then again, good shoes—like good experiences—are investments. Investments in comfort, in adventure, and, ultimately, in yourself. So go ahead, embrace that rolling feeling underfoot and make walking not just a mode of transport, but an experience in itself. After all, the journey is just as important as the destination, perhaps even more so.

Trust me, give these bad boys a spin, and walking will never feel the same again.

  1. Price: At $131.25, the shoe might be seen as a significant investment for some consumers, especially those who are not avid walkers.
  2. Weight: At 13.4oz (380g), some might find the shoe a bit on the heavier side compared to other walking shoes, which could be a factor on longer walks.

  4. Care Requirements: The care instructions suggest treating stains immediately and avoiding heat while drying, which might be a bit cumbersome for some users.
  5. Complex Technology: While the KEEN.CURVE technology offers a unique walking experience, it might take time for some people to get used to this new way of walking, especially if they're switching from traditional footwear.
  6. Not Yet Widely Reviewed: As a newer product, there may not be as many consumer reviews to vouch for its long-term durability or comfort.
