The Kaha 2 is HOKA’s long-haul tank: plush comfort, locked-in stability, and miles of cushion underfoot. The Frost GTX takes that same backbone and fortifies it for deep winter. Think 400 grams of insulation, a reflective foil sockliner, and a compression collar that seals out the cold—all rated down to -25°F. Underfoot, Vibram® Megagrip with 5 mm Traction Lugs claws into frozen ground, while a GORE-TEX membrane keeps snow and slush where they belong—outside. And because it’s HOKA, you still get the high-stack cushion and signature HUBBLE® heel that make rough terrain feel easy. From snowy summit trails to iced-over sidewalks, the Kaha 2 Frost GTX is built to handle winter head-on without sacrificing an ounce of comfort.

About HOKA
Born in the French Alps, HOKA’s unmistakable footwear was originally conceived as the solution to a straightforward problem: go downhill faster during endurance races. The brand’s blend of maximalist cushioning, enhanced stability, and shockingly light weight was quickly embraced by ultramarathoners (for obvious reasons) and their pack of loyal acolytes has only continued to grow. Expanding to encompass all other walks of life where comfort and performance are paramount, HOKA’s mission shows no signs of slowing down any time soon.
