Custom fit system with adjustable last and method for custom fitting athletic shoes

An adjustable footform last for custom fitting footwear having medial and lateral sides, and an instep area, said last comprising:

• a last body;
• a medial adjustment element extending along a portion of the medial side of said last body, said medial adjustment element being movable toward and away from said last body;
• a lateral adjustment element extending along a portion of the lateral side of said last body, said lateral adjustment element being movable toward and away from said last body;
• an instep adjustment element extending along the top of said last body, said instep adjustment element being moveable toward and away from said last body;
• and
• a detent provided on an upper area of the last body above the medial adjustment element, instep adjustment element, and the lateral adjustment element, said detent providing a reference position of the last body within a footwear forming device.

An adjustable footform last for custom fitting shoes having medial and lateral sides and an instep area to an individual wearer's foot measurements, said last comprising:

• a last body;
• a medial adjustment element extending along a portion of the medial side of said last body and movable toward and away from said last body by a medial adjustment mechanism;
• a lateral adjustment element extending along a portion of the lateral side of said last body, said lateral adjustment element being movable toward and away from said last body by a lateral adjustment mechanism;
• an instep adjustment element extending along the top of said last body, said instep adjustment element being moveable toward and away from said last body by an instep adjustment mechanism;
• a width calibration mechanism coupled to said medial adjustment mechanism and said lateral adjustment mechanism such that incremental movement of said width calibration mechanism results in corresponding incremental movement of said medial and lateral adjustment elements to provide width;
• an instep calibration mechanism coupled to said instep adjustment mechanism such that incremental movement of said instep calibration mechanism results in corresponding incremental movement of said instep adjustment element to provide girth adjustment;
• and
• a calibration housing extending from the last body above the medial adjustment element, instep adjustment element, and the lateral adjustment element to house the width and instep calibration mechanisms and having a detent configured to position the last body with respect to a footwear forming device.

An adjustable footform last for producing custom fit shoes based on an individual wearer's foot measurements, said last comprising:

• a last chassis;
• an adjustment mushroom extending along a portion of said last chassis and movable toward and away from said last chassis by an adjustment mechanism;
• a calibration mechanism coupled to said adjustment mushroom such that incremental movement of said calibration mechanism results in corresponding incremental movement of said adjustment mushroom to provide a custom dimension to said last based the wearer's foot measurements;
• a calibration housing extending from the last chassis to house a portion of the calibration mechanism;
• and
• a detent provided on the last to indicate a position of the last to a cooperating device.

An adjustable footform last for producing customized fit shoes for a specific activity and based on an individual wearer's foot measurements, said last comprising:

• a last chassis;
• a first adjustment element extending along a portion of said last chassis and movable toward and away from said last chassis by a first adjustment mechanism;
• a first calibration mechanism coupled to said first adjustment element such that incremental movement of said first calibration mechanism results in corresponding incremental movement of said first adjustment element;
• a calibration housing extending from the last chassis to house the first calibration mechanism;
• and
• a detent provided on the last to indicate a position of the last to a cooperating device.
