Adding straps to a sandal / shoe

Hello friends, I'm new to Autodesk Fusion and have been trying to design some shoes for a doll.

Below is a photo of what I'm going for, along with a screenshot of what I built so far. It was created by modeling the cross section of the shoe first, then modeling the outline of the sole and extruding it up, and finally doing an intersect extrude across. I used a copy of the body and the 'shell' function to get the border around the edge of the top.

How would you go about attaching the toe strap onto this shoe?

I would use T-Splines (Form environment) for this. I would leverage the symmetry in the straps. If you can share the model here, it will be easier to demonstrate on your own model. Otherwise, I will create a dummy model to illustrate, in a bit.

I'm a complete n00b at this. Here's the f3d file.

here is my attempt (on my own version). It's not great, but might give you some ideas of how to proceed. The basic steps were a bit too involved to try to video, but, the basic steps were to create a Plane in TSplines, massage the points around to follow one side of the strap. Eventually, you mirror that one side, and thicken it. I'm attaching the design for reference, but since TSplines has no history, it might not be all that helpful to a beginner. You can probably also model the strap using Sweep, but the path will have to be a 3D curve, which, itself, is a bit complex. I'll think more about this to see if there is a simpler approach.

Amazing, you whipped that up so fast!

OK, here is another approach that is a bit more straightforward, using sweep. It does require a 3D sketch, but there is an easy way to do that with Move.

First, to make everything easier, I wanted to center your design on an origin plane, so we had a good symmetry plane. Fortunately, that was not too difficult:

Then, create an elliptical profile on that center plane, create an offset plane to the center of that ellipse, and create the 3D spline for the path. That starts out as a 2D spline from the top view, and then use Move to move the points vertically. Then, just sweep, and mirror:

the toe strap (is that what you call that thing?) was easy - 2D sketch and Pipe:

final model is attached. It's pretty rough, but will give you some idea how to proceed
