The special purple shoes, which also feature gold chain details on the straps, each featured the names of his children -- 11-month-old daughter True Thompson, whom he shares with Kardashian, and 2-year-old son Prince, from his previous relationship with ex Jordan Craig.
The sweet sneakers are also adorned with his brother's name, Amari, and the custom color is meant to honor Purple Day, which aims to raise awareness of epilepsy -- an ailment his brother suffers from.
"Todays a special day for me and these kicks are very special to me," Thompson captioned his post, which included three shots of the sneakers from different angles.
The messy split grabbed a lot of headlines and lead to a lot of tension and animosity between the various players in the drama, but Kardashian has consistently defended Thompson in his role as a father.
"Khloe has True for the majority of the time," the source said. "Khloe's able to bring True or be with her at work, where Tristan can’t. Also, True spends a lot of time with her big family and all the cousins are in L.A. so it makes the most sense for her to stay with Khloe."
"Khloe and Tristan may have their issues but Khloe will never deny Tristan a chance to spend time with his daughter," the source added. "Things may change in the future, but for now Khloe and Tristan are on the same page with True being with Khloe for most of the time."
