Footwear and a method of manufacture of footwear are presented. The footwear has different insulation zones and each zone has a different level of insulation. For example, an article of footwear includes a first insulation zone, a second insulation zone, and a third insulation zone. The first, second, and third insulation zones each provide a different level of insulation for a specific part of a wearer's foot. The first insulation zone may be the heel region of the article of footwear, the second insulation zone may be the main part of the foot region of the article of footwear excluding both the heel region and a toe region of the article of footwear, and the third insulation zone may be the toe region of the article of footwear.

The invention is an article of footwear incorporating insulation material, such as a low bulk insulation material, to provide warmth in cold weather, yet with the style, agility, and breathability of a typical conventional shoe or boot. Additionally, in a further embodiment, the invention includes these features in a shoe or boot which is also waterproof and breathable. These aspects of the present invention are achieved through a placement, or mapping, of low bulk insulation to maximize the footwear article attributes of warmth, style, agility, and breathability.

Articles of apparel including an encapsulated insulation panel with a plurality of spaced apart insulation sections, methods of making the encapsulated insulation panels, and methods of making the articles of appeal are provided. Methods of making articles of apparel may include bonding an encapsulated insulation panel to a first fabric layer with an adhesive film. Methods of making articles of apparel may also include coupling the encapsulated insulation panel to a second fabric layer with an adhesive tape to form a multilayer fabric. The bonding and coupling of an encapsulated insulation panel to the fabric layers may be performed with using one or more presses.

A shoe has a heated insole with a battery-receiving portion. A battery is insertable into and removable from the battery-receiving portion of the shoe's insole while the insole is disposed within the shoe.
