Through magnifying the training shoe sector, the quantity of content is reduced, making the story more digestible. The rationale behind choosing this sector is due to its very unsustainable history. From the 1960s onwards the trainer industry as a whole is incredibly harmful with dangerous solvents and toxic chemicals being used in production. The consumption has also rapidly increased with every person interviewed had at least one pair of trainers making it an unbiased fashion item.

The decomposition of a trainer is one of the highest within the fashion sector with most shoes taking between 30-50 years to decompose. This concept helped generate a lot of development for story concepts and narrowed the pool of ideas down.
