Alpha Thermal boots are designed with comfort and function in mind, and that includes the plush layer of fleece added to the 7mm of naturally insulating neoprene. 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.
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.
Make winter seem less endless.
The fleece in the Alpha Thermal is extra plush, making them extremely warm and cozy. The thick fleece is in addition to the 7mm of insulating neoprene. You might be out in the cold, but your feet will feel like they’re wrapped in a blanket warming by the fire.
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.
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.
