I feel like everyone is reading "leather shoe" and interpreting it as "dress shoe," but tennis shoes/trainers are usually leather, too. Sandals, moccasins, etc. Leather is a material. My ON running shoes are leather. My legit hiking shoes are leather. So are the kung fu shoes I used twenty years ago to fly through the fucking air with swords.

Probably interpreting it that way because “bad for running” and “needs shoe polish” can’t possible be describing sports shoes with leather components.
