  • Publication number: 20100275465
    Abstract: A footwear assembly configured in accordance with one embodiment of the disclosure includes a footwear product, such as a boot, shoe, overshoe, etc., with a scent blocking extension member removably attached to an upper of the footwear product. The extension member can be tightened around the lower leg or ankle of a user to block scent from exiting the inside of the footwear product. The extension member can be made from material that is treated or otherwise configured to block scent (e.g., human scent). The extension member can be removably attached to the footwear product to allow the user to remove the extension member if not required, or to wash the extension member separate from the footwear product.

  • Publication number: 20100175280
    Abstract: Footwear assemblies including removable enhanced traction devices are disclosed herein. In one embodiment, a footwear assembly includes a footwear product with an outsole that removably receives a traction enhancing device. The outsole includes a tread pattern having a plurality of channels corresponding to portions of the traction device. The traction device includes multiple webs or straps that carry studs or other types of protrusions for improved traction. When a user attaches the traction device to the footwear product, the channels in the outsole removably receive the corresponding webs, thereby positioning the protrusions to extend away from the outsole. The outsole can also include one or more channels extending around one or more peripheral portions of the footwear product (e.g., around the side, back and/or front) to receive corresponding portions of the traction device and retain the traction device on the footwear product.
