What's up, lads? In barely a month, Rubius went from wearing Sporting kit in his most-watched stream to dropping trainers with Siroko. Since you lot keep asking me about it, here's everything linking Rubius and Siroko, in order with dates.
🧭 In short: Siroko is the Gijón brand that kits out Real Sporting. Rubius wore two Sporting shirts from Siroko during his GTA VI stream (August 2026) and a month later MadKat, his brand, launched the MadKat x Siroko ONE trainers with Siroko—the first collab between the two brands.
The timeline
- 2021 to 2025 · MadKat grows. Rubius's brand (formerly RubiusCorp) does collabs with Batman, Rick and Morty, Naruto, Fast & Furious and the Ninja Turtles, and even drops limited-edition keyboards. What is MadKat.
- February 2026 · End of the "first chapter". MadKat announces it's closing one chapter to open another.
- 26 and 27 August 2026 · Rockstar North. Rubius reveals he's visited the GTA VI studio and posts a video with unseen footage.
- 29 August 2026 · The Sporting shirt. During the stream where he shows off the exclusive GTA VI lamp Rockstar sent him, he appears wearing Sporting's black goalkeeper kit and the green one. Both from Siroko. I covered it here.
- September 2026 · The "leak". During a stream, some trainers that didn't officially exist yet are spotted. Leak or strategy?
- Late September 2026 · MadKat x Siroko ONE. Pre-orders open: special edition of the high-top Infinity, four designs and €59.95 per shoe. All the details.
- 19 November 2026 · GTA VI. Game drops on PS5 and Xbox Series X|S, early access from the 12th. We'll have to see what Rubius is wearing that day 😏
What do MadKat and Siroko have in common?
- Japan. The MadKat x Siroko trainers draw inspiration from the duality of Japanese culture, and MadKat's been tapping into anime for years—their Naruto collection was the brand's biggest.
- Editions, not merch. Both brands push limited collections and products with a story behind them.
- Community. Siroko grows with clubs, festivals and creators; MadKat grows with Rubius's community.
And what about Sporting?
Siroko is the kit brand for Real Sporting de Gijón. Having the biggest Spanish-speaking creator wear it in his most-watched stream is a proper moment for the locals. Is he a Sporting fan? He hasn't said. But Rubén, the invite to El Molinón still stands. 🔴⚪
