Waterproof articles of footwear having an improved fit and waterproof stretchable liners are provided. The footwear and liners of the present technology may include various stretchable components configured to tightly secure and conform to a user's foot and adapted to provide a tighter and more versatile fit around the differently sized and shaped feet of various different users. In some aspects of the present technology, the waterproof liner may contain one or more stretchable panels and one or more non-stretchable or less stretchable panels. In other aspects, waterproof footwear may be provided with stretchable components such as straps or bands adapted to secure a user's foot.

Footwear, such as a skate (e.g., a hockey skate), comprising a boot (e.g., a skate boot) or other foot-receiving structure configured to receive a user's foot, in which the boot or other foot-receiving structure is designed to enhance performance, including a range of motion of the user and energy transfer (e.g., to a skating surface while skating or otherwise moving on the skating surface), fit on the user's foot, and/or comfort of the user, such as by having articulated, thermoformable and/or removable parts that may have desired properties in selected regions.

A skate (e.g., an ice skate) for a skater (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the skater and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface (e.g., ice). At least part of the skate boot and optionally at least part of one or more other components (e.g., the skating device) may be constructed from one or more materials (e.g., foams) molded by flowing in molding equipment during a molding process (e.g., injection molding or casting). This may allow the skate (or other footwear) to have useful performance characteristics (e.g., reduced weight, proper fit and comfort, etc.) while being more cost-effectively manufactured. Other articles of footwear are also provided.
