Late-season hunting have your feet frozen solid? Boot Insulators, from ArcticShield, may be the solution. With a polyester outer shell and liner, these boot shields are windproof, water resistant, lightweight and packable. Heat, meanwhile, is kept in by "Retain" technology: an aluminized polypropylene core layer in the fabric, designed to return up to 90% of body heat to the source. To keep a low profile, these insulators are available in RealTree Edge, Mossy Oak Break-Up Country, or basic Black. Sizes, which cover all shoe sizes from 6-13 in mens', and 8-14 in womens', are Small, Medium, Large and X-Large. For more information, please visit arcticshieldoutdoor.com. MSRP: $54.99-64.99.
