The COVID-19 pandemic has forced many Americans to look for side hustles in order to make ends meet, with some turning to the secondary market platform StockX to make extra cash.

StockX is out with its latest Big Facts report, "Pandemic-Era Trends: The Next Chapter," highlighting hot pandemic-era products as well as the sheer volume of sellers who recently joined the platform, which sells sneakers, streetwear, watches, and other collectibles.

The report pointed to Crocs as big sellers during the pandemic. The average resale price of the casual comfort shoe, dubbed “the shoe of the pandemic,” has jumped 70% in Q1 2021 compared to the prior year’s quarter, according to StockX. Another big pandemic play on StockX were Nike Jordan golf shoes, which saw a 150% increase in trades during Q1 2021 compared to the same quarter last year, as the outdoor sport boomed in popularity during the pandemic.

StockX data shows that hundreds of thousands of new sellers have joined the platform since the onset of the pandemic in March 2020, selling $800 million worth of products.
