Katz, who describes himself as "a big sneakerhead," started a company named Stadium Custom Kicks ("SCK"), which customizes baseball cleats. He began by watching online videos to learn how to paint sneakers, and then purchased paint and developed a design. When he first began customizing cleats, the first pair he customized was for himself for the 2017 World Baseball Classic. Rob Refsnyder, a New York Yankee at the time, saw the design on an Instagram account, and direct-messaged Katz, asking: "Hey, can my friend Aaron and I send in a bunch of cleats?” Some individual Major League Baseball players have ordered 20 to 30 pairs of cleats in a single season. While two thirds of his custom projects are baseball cleats, football and golf are close behind. In 2022, the company produced approximately 3,000 pairs of cleats, which were sold for $300 to $600 per pair. As of 2023, 43 people work for the company, including 30 artists. A player works with a designer, and the shoe model a player chooses is sent to one of the artists, who use Jacquard Airbrush Color, which is available in 57 colors and can be mixed to create more. ==See also==
