So, I heat molded these shoes 2 ways.
1) in a toaster over, using an external thermometer as a redundancy, and
2) the steaming method
In both cases, the soles were barely moldable. In both cases the glue started coming undone.
I was able to have the seams stick together, but I am not really sure anything happened with the shoe.
I asked the vendor what the remedy is, and they replied "Use shoe glue"
The Fitgo (BOA) buckles work well so far, and tighten the shoe nicely.
The Speedplay cleat adapter plates did not sit flush against the sole, but that did not seem to affect using the cleats.
To me it just seemed like the cleats simply needed a breaking in period. I used a bit of Fluid Film on it and simply clipped in and out until it became easier.
No issues clipping in now, and no accidental clipping (although I haven't tried them on a steep climb or sprint yet)
Also, I bought 1 size too small it seems. I know road shoes should be more snug, but we'll see how the feet feel after a long ride.
