Abstract: A modular shoe separates into components. The components may be interchangeable to provide versatility without requiring a large number of single use shoes. Each shoe component may also be collapsible to provide for convenient packing in a travel bag or other location where space is limited.

Abstract: The present invention discloses various features and combinations thereof for use with articles of footwear such as boots. The boots are especially adapted for use on construction projects, and provide protection, support and comfort to the wearer. Numerous outsole configurations and styles are provided, which provide superior traction and a low center of gravity for enhanced balance. Different layers of materials provide puncture resistance, abrasion resistance, thermal insulation, waterproofing and other benefits. Protective and/or insulative plates may be utilized in the footwear for puncture protection or thermal insulation, for example. Shovel guards protect the wearer when using a tool, and toe tools permit the wearer to employ the boot as a tool of its own. Structural support cages chimney structures are also utilized for support and comfort.

Abstract: The present invention employs chimneys and chimneys structures to move or vent heat and moisture away from the foot and out of the microclimate of the shoe. The chimneys define pathways that utilize convection and other principles to cool and dry the foot. The chimneys and chimney structures can have many different configurations, and can be positioned anywhere desired in the upper. For example, chimneys can be positioned on the sidewalls of the upper, in the tongue, or both. Chimneys and chimney structures can also be used with form-fitting foot coverings such as socks or leggings, or used with other apparel. Specialized footbeds can also be employed with footwear chimneys to evacuate hot, moist air away from the underside of the foot and towards the chimneys.
