The goal of the entire project (to give an understanding of what I am doing): make sneakers based on my foot measurements, sneakers similar to these (we take as much as possible from this example)

We mainly use a 3D printer

—-------------------------------------------------------------------------------------

Stage №1 ✅ (completed) – create a last and modify its dimensions according to my foot measurements – LAST - https://drive.google.com/file/d/1Ex6t-ZBnWr1aX0tVINxFcvvpiV1UHL8l/view  (available in stp)

Stage №2:

Create a shoe sole (similar to this — similar design; I will provide more images): https://drive.google.com/file/d/1Z8Kc3LF6B3-IPIEljBZAp8CUVRz1JMx4/view?usp=drive_link 

and modify its dimensions so that the last fits inside the created sole.

You must provide 2 files:

1. standard sole;

2. sole that fits our last (modified dimensions) 

Important: I will need to attach a leather upper to the sneaker to the sole. Here is the design I came up with.

How the process generally looks:

A pre-sewn leather upper of the sneaker is placed on the last, and this entire structure is placed on the sole we will make. Then we slide the leather between the upper walls of the sole and stretch everything to create the shape, as well as thread some pieces of leather further into the gaps we have made in the sole. Some parts of the leather will come out the back, where they will need to be fixed (I don’t yet know exactly how). As an option, a temporary structure like this can be used: [link that will also need to be modeled]. After that, we will glue the most important areas. Then we will attach the second sole (most likely using control points for connection and glue, although I would prefer not to use glue).

The sole will be made of foam.

Leather thickness — 1.4 mm.

The goal is to deliver 2 files (in stp): 

1. standard sole;

2. sole that fits our last (modified dimensions) 

And to consider the entire structure I described above
