A skate having a skate boot with a non-lasted boot shell, the shell having a first non-lasted three-dimensional sub-shell and a second non-lasted three-dimensional sub-shell, the second sub-shell being interior to and adjoining the first sub-shell, the first sub-shell comprising a first material having a first density and the second sub-shell comprising a second material having a second density, the second density being less than the first density, the shell being shaped so as to have a heel portion, an ankle portion, a lateral portion, a medial portion, and a sole portion; and a ground-engaging assembly disposed on an underside of the skate. Additional sub-shells are possible. Methods of manufacturing the skate boot shell, including molding and build-up, are also disclosed.

A wearable article such as an article of athletic gear (e.g., a skate, an article of protective athletic equipment such as a helmet, etc.) wearable by a user and comprising an expandable user-engaging structure that is configured to be expanded (e.g., by heat or another stimulus) after manufacturing of the wearable article to conform it to the user or otherwise improve a fit of the wearable article on the user.

A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.

A skate (e.g., an ice skate) for a user (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the user and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface. The skate boot may be constructed by molding (e.g., injection molding) so as to have useful performance and/or characteristics (e.g., reduced weight; enhanced fit, comfort and range of motion; enhanced appearance; etc.) while being cost-effectively manufactured.

The invention discloses a support for a goalkeeper skate and a goalkeeper skate. A support for a goalkeeper skate comprises a protrusion arrangeable on a medial (M) side of the goalkeeper skate. A goalkeeper skate comprising said support is also disclosed. The support and the goalkeeper skate disclosed herein may be used for aligning joints in lower extremities including hip, knee, and ankle joints of an ice hockey or roller hockey goalkeeper.
