About the Founder
Juan Diego Lastra

Juan Diego Lastra is a Puerto Rican designer, maker, and product creator whose work exists at the intersection of sport, culture, and craftsmanship. With a Master's degree in Sports Product Management from the University of Oregon, his background spans product creation, design strategy, consumer insights, and hands-on fabrication. Throughout his career, he has worked across the product lifecycle - from identifying opportunities and shaping concepts to guiding creative vision and bringing ideas to life through development and execution.
Driven by a curiosity for how products influence identity and create emotional connections, Juan has spent his career exploring the relationship between storytelling, design, and innovation. Whether contributing to future-focused concepts alongside global sportswear brands or building one-of-one pieces in his own studio, his work is rooted in the belief that great products should carry meaning beyond their function.
That philosophy led to the creation of Last Annex.
Founded as an independent creative studio, Last Annex emerged from a desire to move beyond the constraints of traditional product creation and explore a more intimate approach to design. Here, craftsmanship, material exploration, and storytelling converge to transform familiar objects into something entirely new. Every project begins with a narrative - a memory, a cultural reference, a moment in time - and is reconstructed through thoughtful design and meticulous execution.
Today, Last Annex specializes in bespoke footwear, reconstructed garments, and creative collaborations that challenge conventional design. Each piece is approached as an opportunity to reimagine the familiar, celebrate individuality, and create objects that feel personal, intentional, and lasting.
Last Annex is not simply about customizing products. It is about preserving stories, honoring craft, and creating objects that feel personal, intentional, and impossible to replicate.
We reconstruct narratives.

What's in a name
last annex — final attachment.
The identity is built like the work itself: a name, a mark, and a twist. The name is a definition. The logo carries a slant. The icon is a shoelace — the last attachment added to a sneaker — and it replaces the double N, holding the technical and the creative in one gesture.
