Allbirds Men's Tree Runner Go Everyday Sneakers - Natural Black (Blizzard Sole) - 13.5 Medium

Your feet deserve better than the daily grind. Most sneakers force you to choose between looking sharp and feeling like you’re walking on clouds, but the Allbirds Men’s Tree Runner Go refuses to play that game. We took the iconic silhouette that put Allbirds on the map and gave it a high-voltage upgrade for the man who’s always on the move.

This isn't just a refresh; it’s a total reimagining of what a daily driver should feel like. The "Go" version features a roomier toe box, allowing your feet to splay naturally and breathe—a game-changer if you’ve ever felt cramped after a few hours of walking. We also reinforced the structure, providing a secure, locked-in feel that doesn't sacrifice that signature Allbirds flexibility. The Natural Black upper paired with the crisp Blizzard Sole offers a stealthy, sophisticated aesthetic that transitions from a casual office environment to a weekend brewery hop without missing a beat.

Performance Meets Pure Comfort
The secret sauce lies in the updated midsole. We’ve packed in even more springy foam cushioning to ensure every step feels energized. Whether you’re sprinting to catch a flight or standing through a long commute, that extra bounce absorbs the impact so your legs don't have to. The upper is crafted from lightweight, silky-smooth tree fibers, creating a cooling sensation that feels incredible even without socks. It’s airy, breathable, and designed to keep you sweat-free when the heat picks up.

Technical Highlights:

• Enhanced Cushioning: A plusher, bouncier midsole designed for all-day standing and high-mileage days.
• Breezy Tree Fibers: Responsibly sourced eucalyptus tree fibers provide a cooling, flexible fit that mimics your natural movement.
• Machine Washable: Life happens. When these get a little dusty, just toss them in the wash on a cold cycle to keep them looking fresh out of the box.
• Roomier Fit: An updated toe box ensures your feet have the space they need to stay comfortable from morning till night.
• Planet-Friendly: Certified Carbon Neutral and B Corp backed, so you can feel as good about your footprint as you do about your style.

Sizing & Styling Tips
In a size 13.5, these are a no-brainer for the guy who needs a bit of extra room. They generally fit true to size, but if you have a wider foot, we recommend sizing up a half step for the ultimate experience. Pair these with dark denim and a crisp white tee for a classic look, or throw them on with tech joggers for your next travel day. When you want a shoe that works as hard as you do, the Tree Runner Go is the only choice.
