If you've ever felt like your run was missing a little something, maybe it was a bit of bounce. What if you could add a literal spring to your stride? That's the idea behind JACK, a running sneaker company with a single, unique selling point: a spring built right into the heel.

This isn't your average, serious running gear. The branding for JACK is all about fun, energy, and a playful sense of comedy. The sneakers are a vibrant, AI-generated vision, and the brand's identity is designed to make you smile. Everything from the logo to the color palette is a bold, energetic statement that sets JACK apart from the competition.

This project includes a complete brand identity system—logo, palette, typography, and marketing materials—to bring JACK to life. It's an invitation to rediscover the joy in running, one bouncy step at a time.
