When temperatures drop and trails turn frosty, two performance icons are stepping up to keep runners moving in comfort and style. Introducing We Run the Cold, an exciting new collaboration from Altra and Smartwool—where Altra’s legendary comfort meets Smartwool’s merino performance.
Together, they’ve created a head-to-toe, merino-based running kit built for those who refuse to let winter slow them down. The star of the collection? The limited-edition Altra x Smartwool Escalante 4 Runners, available now exclusively at MEC in Canada.
Performance Meets Warmth
Available in navy for men and gray for women (both $189.95 CAD), the Escalante 4 keeps Altra’s hallmark zero-drop platform and Original FootShape™ fit, giving runners the natural stride and roomy toe box they love. But now, it’s paired with a Smartwool Merino blend upper that brings natural warmth, moisture control, and breathability to every cool-season run.
Reflective detailing ensures visibility on early-morning starts or post-work miles, while the Altra EGO™ midsole provides responsive cushioning that adapts to both steady training runs and quick tempo efforts. Beneath it all, the FootPod outsole mirrors the anatomy of the human foot—supporting natural movement and flexibility mile after mile.


Run Naturally. Stay Warm. Move Freely.
Whether you’re chasing sunrise kilometres through city streets or logging crisp trail miles as the daylight fades, the Altra x Smartwool Escalante 4 Runners deliver the perfect balance of warmth, comfort, and performance.
Key Features:
- Smartwool Merino blend upper for warmth and breathability
- Altra EGO™ midsole for cushioning and responsiveness
- Original FootShape™ fit for natural toe splay
- Zero-drop platform for a low-impact, balanced stride
- FootPod outsole mapped to your foot’s natural movement
This exclusive drop is available now at MEC—but quantities are limited.
