Holy hell, the Transformers are so incredibly painstaking to draw. Doing this pair has given me an immense amount of respect for both the animators of the original animated series and the comic book artists who continue to add detail to the character designs.
The recipient of this pair is a major fan of the original Transformers, specifically the movie that came out in 1986. For this pair, one shoe is Autobot themed and one shoe is Decepticon themed. The leaders of each faction were good choices for the dominant images. Hot Rod and Starscream snuck onto the inside panels.
The backs feature the logos of the respective factions.
