AI Technical Summary
Existing ski boot fitting methods are inefficient and do not account for individual skier's unique anatomical features, leading to discomfort and poor performance.
A method utilizing 3-D imaging and computer-aided design to create custom-fitted ski boots and footbeds, incorporating a 3-D printer and CNC machine to replicate skier's legs and feet, followed by molding in heated liners and footbeds to match anatomical contours, and adjusting boot flex and stance based on skier's stance and ankle flex calculations.
Custom-fitted ski boots and footbeds provide enhanced comfort and performance by accurately conforming to the skier's anatomy, improving fit and stance alignment.

Abstract
Description
DETAILED DESCRIPTION OF THE EMBODIMENT 1. The invention described herein is a means for purchasing custom fitted ski boot / boots as shown in Fig.7 (3) and custom fitted ski footbed / footbeds as shown in Fig 8. (1) off the internet as shown in Fig.2. (2). Using a smart device (phone, tablet, or watch) as shown in Fig 1 (1), a person as shown in Fig.1 (3) takes photos or video as shown in Fig.1 (1-3) of the skier’s lower leg / legs and foot / feet as shown in Fig 1 (2). These images as shown in Fig.1 (1-3) are then converted to a 3-D image as shown in Fig.2 (1). 2. The 3-D image as shown in Fig.2 (1) is then converted into a computer aided design known as a CAD as shown in Fig.3 (2). The CAD image as shown in Fig.3 (1) is then programed into a 3-D printer as shown in Fig.4 (2). The 3-D Printer as shown in Fig 4 (2) produces a replica of each of the skier’s lower legs and feet as shown in Fig.4 (1). The CAD as shown in Fig.3 can also be programmed into a computer numerical control robot known as a CNC as shown in Fig.5 (2). The CNC machine as shown in Fig.5 (2) is then used to produce a replica of each of the skier’s lower legs and feet as shown in Fig 5 (1). 3. A person as shown in Fig 6 (4) places the skier’s replicated leg and foot as shown in Fig 6 (3) into a heated liner as shown in Fig 6 (2) and heated ski boot as shown in Fig.6 (1). A person as shown in Fig 7 (4) allows the heated liner and ski boot as shown in Fig 7 (2-3) to mold to the replicated leg as shown in Fig.7 (1). A heated ski footbed as shown in Fig 8 (1) is applied to the replicated foot and leg as shown in Fig.8 (2). Theheated footbed as shown in Fig.8 (1) cools to the shape of the replicated foot and leg as shown in Fig.8 (2). The skier’s ankle flex as shown in Fig.9 is determined by a person as shown in Fig.1 (3) taking a video or photos as shown in Fig 1 (1) of a skier standing on a hard surface as shown in Fig.9 (3). While flexing the knees forward, as shown in Fig.9 (2), the point at which the skier’s heels come upwards, as shown in Fig. 9 (1) off the hard surface as shown in Fig.9 (3), determines the skier’s ankle flex as shown in Fig.9. The skier’s ankle flex as shown in Fig. (9) is used to determine the ski boot flex Fig. (9) of the custom ski boot. Fig.7 (3). 4. The skier's correct stance as shown in Fig.10 is determined by a person as shown in Fig 1 (3) taking a photo as shown in Fig 1 (1) of a skier with bent knees as shown in Fig 10-1. Using computer software as shown in Fig 3. (2), a line as shown in Fig.10 (2) is drawn from two thirds of the knee mass as shown in Fig.10 (1) to the second toe as shown in Fig 10. (3). This calculation as shown in Fig.10 (1-3) is used to customize the ski boot as shown in Fig.7 (3) so that the skier’s foot and leg, while in the ski boot, as shown in Fig.7. (1-3) have the correct stance as shown in Fig.10.
Claims
1 CLAIMS [0001] Said process of taking a digital recording of said skier’s lower legs and feet and converting said skier’s lower legs and feet into a 3D image. This 3D image of said skier’s lower legs and feet is then programmed into a computer assisted design known as a CAD. The CAD of said skier’s lower legs and feet is then read by a 3D printer or a computer numerical control robot known as a CNC. The 3D printer or CNC robot is then used to produce said replicas of said skier’s lower legs and feet. Said replicas of said skier’s lower legs and feet are then used to produce a pair of custom ski footbeds and a pair of custom ski boots.
