Abstract
A golf shoe with a sole assembly having a regionally time-dependent midsole is provided. The midsole may include a lateral region constructed of a first material and a medial region constructed of a second material, where elastic properties of the lateral region and viscoelastic properties the medial region provide a neutral support platform when a relatively brief compression load is placed on the midsole (e.g., when a wearer is taking a step while walking), and further provide an everted supported platform when the compression load is placed on the midsole for a longer period of time (e.g., when the wearer is swinging a golf club).
Claims20
A golf shoe comprising:
- an upper;
- and
- a sole assembly connected to the upper, the sole assembly comprising:
- an outsole;
- and
- a midsole comprising:
- a lateral region constructed of a first material;
- and
- a medial region constructed of a second material, wherein:
- the first material compresses to a maximum compression of the first material within a first time period;
- and
- the second material compresses to the maximum compression of the first material within the first time period and compresses to a maximum compression of the second material within a second time period.
A regionally time-dependent midsole for a golf shoe, the midsole comprising:
- a lateral region constructed of a first material;
- and
- a medial region constructed of a second material, wherein when the midsole is under a load:
- the lateral region compresses to a maximum compression of the first material and the medial region compresses to the same maximum compression of the first material within a first time period;
- and
- the medial region compresses to a maximum compression of the second material within a second time period.
A method for making a golf shoe comprising a regionally time-dependent midsole for a golf shoe:
- constructing an upper;
- constructing an outsole;
- constructing a lateral region of a midsole using a first material;
- constructing a medial region of the midsole using a second material, wherein:
- the first material compresses to a maximum compression of the first material within a first time period;
- and
- the second material compresses to the maximum compression of the first material within the first time period and compresses to a maximum compression of the second material, higher than the maximum compression of the first material, within a second time period;
- attaching the lateral region to the medial region of the midsole;
- generating a sole assembly by attaching the midsole to the outsole;
- and
- attaching the upper to the sole assembly.
