Abstract
A sole structure for an article of footwear includes a chamber having a first barrier element, a second barrier element, and a tensile member. The tensile member is disposed within an interior void defined by the first barrier element and the second barrier element. The sole structure further includes a phase change material disposed within the interior void and operable between a first state in a first temperature range and a second state in a second temperature range. The first temperature range is from 30° C. to 35° C. and the second temperature range is from 35° C. to 42° C. The sole structure further includes an insulating member disposed between the chamber and a ground contacting surface.
Claims17
A midsole for an article of footwear, the midsole comprising:
- a chamber including a first compartment separated from a second compartment, each of the first compartment and the second compartment including a first barrier element, a second barrier element, and a tensile element disposed within an interior void defined by the first barrier element and the second barrier element;
- and
- a phase change material disposed within each interior void and operable between a first state having a first viscosity and a second state having a second viscosity greater than the first viscosity, the phase change material includes a first material and a second material, the second material having a phase transition temperature different than the first material, the first material entirely disposed in the first compartment and the second material entirely disposed in the second compartment.
A midsole for an article of footwear, the midsole comprising:
- a chamber having a first compartment separated from a second compartment, each of the first compartment and the second compartment defining a respective interior void;
- a respective tensile member disposed within each interior void, each tensile member respectively attached to opposing surfaces of the first compartment and second compartment of the chamber;
- and
- a phase change material including a first material and a second material, the first material entirely disposed within the interior void of the first compartment and the second material entirely disposed within the interior void of the second compartment, each of the first material and the second material being operable between a first state in a first temperature range and a second state in a second temperature range, the first temperature range and the second temperature range of the first material being different than the first temperature range and the second temperature range of the second material, respectively.
A midsole for an article of footwear, the midsole comprising:
- a chamber having a first compartment separated from a second compartment, each of the first compartment and the second compartment defining a respective interior void, the first compartment including a first phase change material and the second compartment including a second phase change material that is different from the first phase change material, and a respective tensile element disposed within the interior void of the first compartment and within the interior void of the second compartment, wherein the first phase change material and the second phase change material are operable between a first state in a first temperature range and a second state in a second temperature range, the first temperature range being different than the second temperature range;
- an outsole defining a ground-contactable surface;
- and
- an insulating member disposed between the outsole and the chamber.
