Work or play, one thing is for certain: Alpha Thermal boots keep feet warm. They’re built with comfort and function in mind. The proof is in the 7mm of naturally insulating neoprene combined with fleece lining. What’s more, their thick EVA midsole provides added insulation underfoot when standing on frozen ground, snow or ice. Don’t fight the cold, embrace it. And by that, we mean let a pair of Alpha Thermals embrace your feet.

Make winter seem less endless.


Alpha Thermal boots are built with 7mm of insulating neoprene and full fleece lining for added warmth and comfort. On a sled, ATV or just walking the dog, these boots will help you handle the worst winter throws at you.

Waterproof, warm, comfortable. The trifecta of winter boots.


LaCrosse Alpha Construction combines our premium, natural rubber with insulating neoprene. Each piece of rubber is hand-laid over the neoprene sock to create a waterproof, durable and comfortable boot. Alpha Thermal boots also feature Active Fit, providing a more athletic and glove-like feel. Thanks to its neoprene core, you get foot-hugging cushion all around and added flexibility to slide the boot on and off.

They keep you on your feet where others fear to tread.


What will help you trudge through all that snow and ice? The outsole. The Alpha Thermal has a rugged, multidimensional lug pattern which is ideal for cold weather traction, keeping your feet where they should be: under you.

Easy on. Easy off. It’s that simple.


Winter boots can sometimes be difficult to pull on. Alpha Thermal boots have textured finger grips and an angled top band so you can easily grab hold and pull them on, even when wearing gloves or mittens. And when it’s time to come in from the cold, a molded kick-off heel plate makes for easy hand-free removal.

More room if you need it, or less room if you don’t.


Our signature gusset is added to each pair, by hand, for best-in-class versatility. This makes the boot easy to roll down to dry it out, and also provides extra room to get in and out of the boot. Opening the gusset makes it easy to tuck in pants, and it accommodates various leg sizes, expanding for larger calves and cinching down for smaller ones.
