'Jelly shoes'

These shoes were once common among coastal dwelling people. Their name is believed to derive from the fact that the shoes were fabricated entirely from processed jellyfish. These had become the dominant species in coastal waters in the mid to late Oil Age as result of ocean warming and over-fishing. Entrepreneurs were keen to find commercial uses for these creatures, given their overwhelming abundance but relative unpalatability. Many items of clothing and household goods were trialled, including jelly beds and wobble boards. Jelly shoes were, however, the only commercial success, being especially popular with children who wore them to play and swim on pebbly shores.
