Enter the Terra® Stormbreaker with its eight-layer TERRASPHERE+™ liner engineered with PrimaLoft™ and Thermolite™ insulations, plus a Mylar heat-radiating film.

The high-traction rubber outsole stays flexible in extreme cold as the micro-diamond texturing and sawtooth lug profile dig into the frozen earth. A CSA Grade 1 composite toe, composite plate and electric shock resistance keep you safer on the job.
