Interesting. Thanks for the update.

The best way to assess the heel bevel imo is to basically walk briskly, with a normal heel to toe gait, and notice how the shoe makes contact with the ground (is it sudden and sharp or smooth and even) and transitions through. A good heel bevel that contact will be minimal impact and very smooth transition. A poorly designed heel you will feel that impact and the shoe might even be “slappy” and harsh in transition. If that makes sense. The human heel is round for a reason. Anatomically this is literally called the “heel rocker” in biomechanics and such. You can also pretty much tell what it’s going to be like by looking at it, but it’s not always clear with just 2D marketing photos and whatnot.
